A Pneumonia Diagnosis Can Have A Major Impact On Health
Pneumonia is an infection in which the air sacs of one or both lungs fill with pus and other fluids. Its caused by bacteria, viruses or fungi and can have a major impact on a persons health and well-being. It can take days – even weeks – to recover from pneumonia, depending on the severity.
For any lung issue, but especially those that can develop quickly into life-threatening infections, it is important to seek care from a pulmonologist that is specially trained in pulmonary infections. We have an entire team of highly trained and experienced pulmonary specialists at University Hospitals.
Expert Pneumonia Care For Geriatric Patients
Pneumonia can affect geriatric patients more significantly and can quickly develop into a life-threatening risk. As a result, the geriatric specialists at University Hospitals collaborate with pulmonary specialists whenever an older patients lung health is at risk. There are a number of reasons why pneumonia puts older patients more at risk:
- The immune system declines with age, making it harder to fight infections.
- Lung function decreases with age, and senior adults aspirate more often.
- Older adults may have other medical problems such as arthritis or heart disease. The presence of additional conditions makes it more difficult to recover from pneumonia.
Thats why our specialized teams at University Hospitals work together to create pneumonia treatment plans that minimize each patients lung discomfort and reduce pneumonia symptoms as they recover.

Although the initial wave of the SARS-CoV-2 pandemic has abated in many countries, healthcare providers are still looking to identify as many COVID-19 patients as possible and contain the disease. Fast and accurate diagnosis is especially important when unsuspecting patients with a coronavirus infection come to the hospital with health complaints but dont yet show symptoms of COVID-19.
Nasal swab samples analyzed by RT-PCR are currently recommended for the diagnosis of COVID-19, however, supply shortages, a wait time of up to two days for results, and a false negative rate as high as 1 in 5 mean alternative, large-scale COVID-19 screening tools are still being sought.
SARS-CoV-2 is known to damage lung tissue, and in a distinct way that doctors are now seeking to exploit for new diagnostic approaches. Many COVID-19 patients develop pneumonia, which can progress to respiratory failure and sometimes death. COVID-19 pneumonia is different from more common forms of bacterial pneumonia, and the differences show up in chest CT scans. Most striking are cloudy lesion patterns that resemble shards of glass or reticular lines within the opaque lesions that look like irregular paving tiles, which occur around the peripheries of both lungs. Lesions from bacterial pneumonia are usually concentrated in one lung and may not resemble shards of glass.

But the coronavirus doesn’t always show up in scans right away.
“We can’t rely on CT alone to fully exclude presence of the virus,” Michael Chung, the lead author of the Lanzhou study, said on February 3.
Lakhani said CT scans are “one of four or five things” needed to make a diagnosis, along with symptoms, clinical history, the progression of the disease, and the laboratory test.

Why You Should Undergo Yearly Lung Cancer Screenings If You’re At High Risk Of Lung Cancer
Lung cancer screenings are like mammograms or colonoscopies: a yearly test that checks to see whether high-risk individuals have developed suspicious signs of cancer, or if cancer does develop, helps catch it as early as possible.
While mammograms and colonoscopies have garnered significant awareness over the years, the percentage of people who undergo yearly lung cancer screenings is very low. In fact, among people eligible for yearly lung cancer screenings in the United States, only about 3 percent get screened.
The United States Preventive Services Task Force advises that you’re at high risk of lung cancer if both of these apply to you:
- Youre between the ages of 50 and 80.
- Youre either a current smoker or a former smoker who smoked a pack a day for 20 years and quit smoking less than 15 years ago.

Limitations And Expectations Of Vp
The imaging manifestations of COVID-19 are diverse on chest CT, with acute pulmonary exudation and interstitial changes being the main features . GGOs, consolidation, linear opacities in the pulmonary peripheral area are the predominant imaging findings of COVID19. However, they are not exclusive in COVID-19, bacterial, mycoplasma, chlamydia, and other viral pneumonia may have similar imaging changes . Meanwhile, there is a time interval between radiological changes and symptom onset and nucleic acid results in some cases.
Despite the shortcoming, we believe up until now VP-RADS 1.0 is an important documentation for a standardized imaging diagnosis and reports. The employment of the system makes it possible to objectively assess the patients COVID-19 risk, and to quickly issue critical reports for timely epidemic containment. VP-RADS helps to set up triage in waiting areas, and is able to recognize high-risk patient and severe cases efficiently, leading to well deployment of medical resources.
The knowledge on imaging evolution of COVID-19 is still in need of more data to evaluate meanwhile, we are also challenged with certain problems raised upon, including potential risk of cross-infection, radiation hazards by CT scans, the false positive and false negative results, all of which are worth further exploring and investigating.
What Is Lung Ct Screening & How Does It Work
Lung CT screening provides more detailed information than conventional X-rays making it possible to diagnose & manage lung cancer earlier & more effectively.
Computed Tomography, commonly known as CT or CAT scanning, is a non-invasive diagnostic tool. CT uses a specialized form of X-ray, coupled with computer technology, to produce cross-sectional images of soft tissue, organs, bone and blood vessels in any area of the body. CT lung cancer screening has revolutionized medical imaging by providing more detailed information than conventional X-rays and, ultimately, offering better care for patients.
Imaging methods to examine the lungs include chest X-ray, low-radiation-dose chest Computed Tomography and standard-radiation-dose chest CT. Low-radiation-dose CT is appropriate for cancer screening because it has been demonstrated to be more sensitive than X-ray in detecting cancer, with less radiation exposure than standard chest CT.
CT technology is used to detect pulmonary nodules, collections of abnormal tissue in the lungs that may be early manifestations of lung cancer. These nodules are often detectable by CT before physical symptoms of lung cancer develop. Early detection of pulmonary nodules through CT screenings has been shown to improve survival compared with patients not undergoing lung CT scan.

Current Limitations In The Diagnosis Of Pneumonia
An ideal reference diagnosis for pneumonia should be based upon the detection of pathogenic agents in lung parenchyma, along with suggestive clinical findings. However, this cannot be carried out in routine clinical practice for evident practical reasons. Hence, pneumonia is usually suspected in the presence of respiratory and infectious signs and symptoms, and confirmed by the demonstration of a new lung infiltrate on a radiologic examination. Unfortunately, signs and symptoms are neither sensitive nor specific, leading to a poor predictive value of clinical data for the diagnosis of chest X-ray or computed tomography -proven pneumonia .
The clinical diagnosis of pneumonia is even more difficult in elderly patients, because symptoms are less specific, and decompensated comorbidities can further blur the clinical picture . The prevalence of most symptoms, including fever and shivers, is reduced with increasing age . Elderly patients tend to report symptoms less accurately because of memory disorders or delirium. Finally, the incidence of alternative diagnoses to pneumonia , and the prevalence of chronic respiratory conditions is also increased in elderly patients .
World Health Organization Advice For Avoiding Spread Of Coronavirus Disease

Benefits Of The Early Detection Of Lung Cancer
Theres a significant difference in lung cancer survival rates between cancers diagnosed in the early stages and those diagnosed at stage 3 or stage 4which is when the majority of lung cancers are diagnosed.
When lung cancer is found when its localizedmeaning theres no evidence its spread outside the lungsits much easier to treat than when its spread to regional or distant areas of the body.
- Chest pain when coughing or laughing
- Unexplained weight loss
- Lung infections that wont go away
Many patients with lung cancer, though, dont have any symptoms until the cancer has advanced to the distant stage. This initial lack of symptoms is why most lung cancers are diagnosed after theyve advanced.
Once patients do experience symptoms, however, researchers found that the average amount of time between seeking medical attention for those symptoms and the start of treatment was 138 days. Such a delay gives the cancer even more time to grow and metastasize and leads to higher anxiety levels for the patient.
This is why getting the appropriate tests to determine whether a nodule is cancerous is so important, even if you dont have any other risk factors for lung cancer.
At CTCA, we recommend you undergo yearly lung cancer screenings if you’re at high risk of lung cancer , even if your lung nodule turns out to be benign.
I Had My Scan Now What
After your CT scan, you are able to return to your regular activities. Make a plan to meet with your doctor to discuss the results, which are typically ready within a few days. Your doctor will review the report and images, and discuss and recommend next steps, if any. You may need to repeat the CT scan within a specific time frame however, it is possible you will be asked to go for additional testing or a procedure such as a biopsy. You can always ask for a copy of your CT scan images for your own records.

What Can I Expect During A Ct Lung Scan
A computed tomography lung scan is a noninvasive X-ray examination. Its purpose is to create precise images inside the body, specifically the lungs in this case. The term “noninvasive” refers to the fact that doctors don’t “invade” the body with surgical instruments to perform a CT lung scan. The images produced from such a scan are a little more in depth than a typical X-ray examination.
If you need to undergo a CT lung scan, it’s always beneficial to know what you’re getting yourself into. Including preparation, each scan will take about 30 minutes. The time actually spent scanning is actually very short, usually just a few minutes. During the scan, a tube hovers around your body and makes whirring, clicking and buzzing noises. This is the scanner taking the pictures.
Before the scan, you will be asked to remove any eyeglasses, jewelry or other metallic objects. Additionally, the technician may ask you to remove any dentures or hearing aids. It’s important to tell the technician if any part of your chest is pierced, because it may interfere with the examination.
Ct Scans Show What Coronavirus Did To The Lungs Of Covid
Medical imagery of people suffering from COVID-19the disease caused by the SARS-CoV-2 coronavirusshows how the condition affects the lungs of patients.
CT scans have become the “first line of defense” in diagnosing suspected infections, especially given the current shortage of testing kits, according to Radiological Society of North America which has published a series of images in several scientific papers.
Among the studies is one paper published in the RSNA journal Radiology: Cardiothoracic Imaging which describes the case of a 44-year-old man who was a transportation staff member in the Huanan seafood market in Wuhan, Chinawhich is thought to be where the outbreak originated.
The man had been suffering from high fever and coughing for 13 days when he was admitted to hospital on December 25, 2019. There he was diagnosed with severe pneumoniaa condition characterized by inflammation of the air spaces in the lungsand acute respiratory distress syndrome, according to the study.
Eventually, doctors diagnosed him with COVID-2019 after ruling out infection with other pathogens which can lead to pneumonia. Despite efforts to save him, the man unfortunately died around one week later.
These kinds of abnormalities are also seen in patients suffering from SARS and MERS which are both in the coronavirus family of SARS-CoV-2.

An Analysis Of Nearly 140 Coronavirus Scans Suggests That Patches Of Ground Glass On Both Lungs Are A Hallmark Of The Virus
Researchers analyzed scans from patients at the Zhongnan Hospital of Wuhan University, the majority of whom were older men with preexisting health problems. The images above are scans from a 52-year-old patient.
The first group of scans were taken on January 7, five days after the patient started displaying symptoms. They show patches of ground glass at the bottom of both lungs.
The man was put on life support from January 7 to 12. After that, his condition seemed to improve. The second set of scans , taken January 21, show that many of the white patches either shrunk or disappeared.
Flexible Fibreoptic Bronchoscopy With Lung Biopsy
Fibreoptic bronchoscopy with bronchoalveolar lavage utilizing a protected brush is a well-established technique in the diagnosis of pulmonary infection. Although this technique may play an important role in the diagnosis of pulmonary infection, the yield of bronchoalveolar lavage is variable and sometimes the diagnosis of a pulmonary infection cannot be established , . This method has proved particularly useful in the diagnosis of Pneumocystis pneumonia in AIDS patients, providing an aetiological diagnosis in â¼95% of cases.
In the special setting of a serious pulmonary process and lack of definable cause with noninvasive methods, fibreoptic bronchoscopy in conjunction with transbronchial lung biopsy is indicated .

Coverage For Lung Cancer Screening Has Been Expanding In The Private Market Even Before A
Coverage for lung cancer screening has been expanding in the private market, even before a decision last week to have Medicare cover it for more patients.
The Centers for Medicare and Medicaid Services announced the national coverage determination Thursday, expanding coverage for low-dose computed tomography for Medicare patients in line with current recommendations, like those from the U.S. Preventative Services Task Force.
The decision expands eligibility so that people with Medicare can get lung cancer screening with LCDT starting at age 50, down from 55. Separately, the screening is now covered by Medicare for people whose smoking history includes consuming 20 packs per year. Previously, LCDT was only covered by Medicare for those who smoked 30 packs per year. While most Medicare beneficiaries are 65 and older, younger people with chronic conditions like kidney failure are also covered by the governmental insurer.
The announcement from Medicare shows that the agency is catching up to coverage already offered by private insurers.
UnitedHealthcare commercial has already implemented consistent with USPSTF guidance, said Heather Soule, a spokesperson for the nations largest insurer, in an email.
Ethan Slavin, a spokesperson for Aetna echoed that.
Anthem, Cigna and Humana and the industry trade group AHIP did not respond to requests for comment Friday for more information on commercial coverage for lung cancer screening.
