    Excluding PTV from lung volume may better predict radiation pneumonitis for intensity modulated radiation therapy in lung cancer patients
    Background Lung dose-volume histogram (DVH) in radiotherapy could be calculated from multiple normal lung definitions. The lung dosimetric parameters generated from various approaches are significantly different. However, limited evidence shows which definition should be used to more accurately pre...

    Association of Target Volume Margins with Locoregional Control and Acute Toxicities for Non-Small Cell Lung Cancer Treated with Concurrent Chemoradiation Therapy
    Traditionally, clinicians based the clinical target volume (CTV) margin for locally advanced non-small cell lung cancer (NSCLC) on early pathologic series suggesting most microscopic disease falls within 5–9mm of the gross tumor volume (GTV) (1–3). Additionally, clinicians formed the planning target...

    Difference in target definition using three different methods to include respiratory motion in radiotherapy of lung cancer
    Introduction: Minimizing the planning target volume (PTV) while ensuring sufficient target coverage during the entire respiratory cycle is essential for free-breathing radiotherapy of lung cancer. Different methods are used to incorporate the respiratory motion into the PTV. Material and methods...

    Original Report Excluding either gross tumor volume or planning target volume from the normal lung volume in lung cancer irradiation: Evaluation of the dosimetric impact
    Purpose When evaluating dosimetric parameters predictive of lung toxicity in lung cancer, the total lung volume can be defined to exclude the gross tumor volume (lung-GTV) or to exclude the planning target volume (lung-PTV). The purpose of the study was to evaluate the impact of these 2 types of de...

    Optimal Clinical Target Volume of Radiotherapy Based on Microscopic Extension around the Primary Gross Tumor in Non-Small-Cell Lung Cancer: A Systematic Review
    Simple Summary As radical radiation therapy for non-small-cell lung cancer becomes increasingly precise following the development of techniques such as image-guided radiotherapy and intensity-modulated radiotherapy, how we define the clinical target volume (CTV) is crucial. Although assessing the s...

    Does omission of CTV in lung cancer radiotherapy compromise local tumor control?
    Decades of experience led to the conclusion that 45–50 Gy results in high control rates for subclinical disease in patients with epithelial tumors ( 3 - 6 ). However, recent studies have shown that omission of the CTV in lung cancer radiotherapy does not compromise local tumor control ( 7, 8 ).

    What are the ways to heal lungs after a COVID-19 infection?

    Dr. Himabindu Sreenivasulu

    MBBS · 1 years of exp

    To aid lung recovery after a COVID-19 infection, prioritize gradual exercise to build lung strength, engage in deep breathing exercises to expand capacity and clear mucus, maintain hydration to keep mucus thin, consume a nutritious diet, get ample rest, and diligently follow your healthcare provider's guidance, including any prescribed medications or oxygen therapy. Keep in mind that recovery varies among individuals, so personalized advice from a healthcare professional is essential for the best approach to healing your lungs post-COVID-19.

    What is the difference between IGTV and respiratory amplitude?
    Respiration can be included in the target delineation process creating a respiratory GTV, denoted iGTV. Alternatively, the respiratory amplitude (A) can be measured based on the 4D-CT and A can be incorporated in the margin expansion. The GTV expanded by A yielded GTV + resp, which was compared to iGTV in terms of overlap.

    What is the difference between IGTV and GTV + resp?
    The overlap between iGTV and GTV + resp showed that on average 7% of iGTV was outside the GTV + resp implying that GTV + resp did not capture the tumor during the full deformable respiration cycle. A comparison of the PTV volumes showed that PTVσwas smallest and PTVΣlargest for all patients.

    Is there a type of pneumonia caused by COVID-19?

    Dr. Pooja M

    MBBS · 2 years of exp

    Yes. The virus which causes COVID-19 can infect the lungs causing pneumonia. About 15% of people with covid 19 can develop covid pneumonia. The symptoms are difficulty in breathing, confusion, tiredness, fever, cough, and chest pain. Covid pneumonia is caused when the immune system attacks an infection of SARS-COV-2 in the lungs. Because of this the alveoli which are the small sacs in the lungs swell and leak fluid.

    Can COVID-19 cause granuloma of the lung?

    Dr. Himabindu Sreenivasulu

    MBBS · 1 years of exp

    COVID-19 primarily affects the respiratory system, and while it can lead to lung inflammation and damage, there isn't significant evidence to suggest a direct link between COVID-19 and the development of granulomas in the lungs. Granulomas are small areas of inflammation often caused by the body's response to infections, immune disorders, or certain environmental exposures. If you have concerns about your lung health, it's best to consult a healthcare professional for accurate information and proper evaluation.
