How accurate is CT with contrast for lung cancer detection?

See answer. Pulmonary ct is extremely sensitive in identifying lung nodules. When found, these nodules then need to be appropriately evaluated either with followup lung ct, pet-ct, or direct tissue sampling. Your clinical dr. Can best advise you – or you can be seen at a dedicated lung nodule center.
It is very accurate. Ct scans are the best way to detect early lung cancers. No test is perfect but cancers slightly smaller than 1cm can be found.

If small cell lung cancer grows so quickly, why is the primary often difficult to visualise on CT with contrast? Is the primary slow growing? Thanks.

Observation. It is not clear why small cell lung cancer can have larger secondaries than the primary lesion. But it is a common observation and metastatic lesions/secondaries may be the first manifestation of this cancer and the primary may be difficult to visualize. It is not due to the slow growth rate of the tumor. Read more...

How accurate is a ct scan for lung cancer and espohagal cancer?

Depending. on the technical factors of the scan, highly sensitive for detecting lung cancer, less so so for esophageal cancers. Small esophageal cancers may be undetectable on CT, endoscopy is the best way to evaluate for that possibility(also biopsy can be performed at the time of endoscopy). Read more...

Imaging - is contrast enhanced ct useful for finding early small cell lung cancer? I understand low dose ct is not good for early sclc is this true?

You need a good Doct. You are getting too deep into medical areas which are beyond your comprehension. You will benefit from seeing a medical doctor(Internist) who can counsel you and guide you further by educating you about your health concerns which appear to be way beyond reason. Read more...

31 m - Is a bronchoscopy / chest Ct scan with contrast and Vq scan good enough to rule out lung cancer or lung problems?

Lung problem. Ct scan can rule out lung cancer. VQ scan only evaluate for pulmonary embolism. Bronchoscopy evaluates for lung infection and certain intrabronchial lung cancer, but it cannot completely rule out lung cancer. One can still have lung problem (e.g Asthma) with all above test being normal. Read more...
Lung cancer. A chest ct scan is usually adequate to screen for lung cancer. VQ scan is used to check for blood clots in the lung. Bronchoscopy is done to obtain and study lung secretions mainly for infectious disease but also to look for malignant cells when malignancy is suspected after other studies have shown a lesion. Lung disorders like emphysema, asthma, pulmonary hypertension are diagnosed by other mean. Read more...
Lung eval. That is a very through evaluation and should be sufficient . You could see masses, tumors, emphysema, frbrrosis, note if abnormal cells, tell if there are emboli. Adding pulmonary function testing (PFTs) would assess the function i.e. tell if you have asthma . f/u/ w/ doc. Read more...
That is a fairly. comprehensive work up and would likely be sufficient for most issues. Pulmonary Function Tests(PFTs) would be useful to evaluate for obstructive airway disease if that is a consideration. Read more...

Besides 30 pack year history, what are other reasons to recomend CT scan for lung cancer screening? Is this the most accurate predictor of risk?

The initial study, . ..If i'm not mistaken, was done on 55-79 year old men with 30 pack years smoking history. Us preventive task force's recommendations eliminated gender but still stuck with the age group, which is older than you. Whether you need it or if it will be covered, will have to be a decision between your doc and you. Screening for lung cancer does not predict risk, it's purpose is to reduce risk.... Read more...
Symptoms. Cough, unexplained weight loss. Hemoptysis- cough blood ct finds a lesion but not prognosis. That is size, cell type, staging dependent. Read more...
Yes. Currently smoking history is best predictor of risk for smoking associated lung cancers, other known predictors are presence of COPD and prior personal history of lung cancer and significant exposure to aerosolized asbestos. Talk with your PCP if concerned, a case for screening can be made for individuals based on unique combinations of risk factors. Read more...

If having Low-dose spiral CT scan chest, or low dose helical CT scan chest, is contrast media injection normally required? Checking lung cancer.

No. If the scan is bring done to screen to screen for lung cancer in a high risk patient (more than 50 pack years) with no symptoms then IV contrast is not used. If the patient has a known lung cancer and has had surgery or chemo radiation therapy, most places would use IV contrast. Read more...
No, the low dose screening protocol does not require IV contrast. Read more...
