Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

Doubt it: If any irregularities in the intestinal wall were found, it would be just that, irregularities. Their presence would suggest a problem but the overlap with other possible conditions would make the information inconclusive. A normal study would also not rule out the condition. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Radiation from CT: This issue should be discussed with your pulmonary doctor and radiologist. There is some risk associated with the radiation from multiple ct scans. However, that risk is likely small compared to the risk of a nodule identified in the lung, and may not outway the risks of ct, in the long run. There should be a plan with a reasoned approach that minimizes the risk of ct that you can agree with. ...Read more

+ PPD test, CT scan solitary pulmonary nodule. 5mos after nodule stable/slight increase pet2.9suv bronchoscopy inflammatory no cough doc said remov?

Curious: More information is required. The pet uptake (measured in standard uptake value or suv), is low level, but not low enough to guarantee benignity. Given age and + ppd, i would suspect this could be an active granuloma. Given your age, i would encourage consultation with a pulmonologist and full review of all your records first. Lung surgery is serious business. ...Read more

PET/CT: I favor a PET/CT in view of its sensitivity. The nodule is large enough for modern scanners to detect any increase in activity. Also the entire body can be checked for any abnormal activity. Best wishes ...Read more

Endocrine issues + fatigue. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT be missing SCLC. Is repeat scan necessary?

Endocrine issues + fatigue. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT be missing SCLC. Is repeat scan necessary?

By SCLC, I presume: you mean small cell lung cancer...a type of lung cancer that is aggressive and is a neuroendocrine tumor which can produce ectopic hormones. But it certainly wouldn't be the first thing you would think of if you have "endocrine issues." The thyroid, pituitary, adrenal glands need full evaluation as well as other work-up. If lung CT "clear" would not pursue SCLC as cause. Best wishes:) ...Read more

Serial Chest CT for lung nodules, one mediastinal node noted 2 yrs ago, recently more nodes are visible. Hx of papillary bladder ca. Follow up needed?

Serial Chest CT for lung nodules, one mediastinal node noted 2 yrs ago, recently more nodes are visible. Hx of papillary bladder ca. Follow up needed?

Bladder cancer: Definitely need follow up. It would be uncommon to have had a papillary bladder ca that spread to the lungs. If there is concern about a new ca I would recommend a PET scan. It could also be related to the lung nodules...etiology? Lymph nodes are seen when there is infection, inflammation, or ca. There are other things like sarcoid that can enlarge nodes. ...Read more

Could a cta chest scan with IV contrast detect problems with the heart?

Not best: Test for heart but sometimes we see things like coronary artery disease and large atrial septal defects. Aortic valve disease can sometimes be seen. Best to have appropriate test for the portion of the heart your doc is worried about. ...Read more

Ct chest scan showed several small 2 mm noncalcified but stable pulmonary nodules in both lungs.Should i be concerned. What symptoms could this cause?

Ct chest scan showed several small 2 mm noncalcified but stable pulmonary nodules in both lungs.Should i be concerned. What symptoms could this cause?

Probably not: 2mm nodules are quite small. If these nodules have not grown(monitored by ct) over significant period of time (months), the likelihood of malignancy is small. These are probably granulomas or scar tissue secondary to previous infection. ...Read more

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Why worried?: Why are you worried? Do you have symptoms or abnormal labs? If the ct was normal and used a specific pancreas protocol, then an MRI of the pan creas may be the best next test. Since it does not use radiation, there is little risk for you. ...Read more

Lung tumor CT scan with or without contrast?

Lung tumor CT scan with or without contrast?

Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...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

No smoker, chest pains, hemopsys. Multiple CT scn in life. Ct shows a calcified left hilar lymph node.  Negative TB should I be concerned with cancer?

Not if it isn't: changing over time. and small. large are likley cancer. Most commonly associated with fungal infections (not active, previosu ones). would expect a cancer to change in size and shape. Some shapes that are regular are not cancer (bulls eye circles of calcium). Without an actual examination, I cannot give specific medical advice on your particular health,. ...Read more

I just had an angio pulmonary cat scan with contrast to rule out a pulmonary embolism. Can that detect lung cancer? Chest xray normal. 42 years old.

I just had an angio pulmonary cat scan with contrast to rule out a pulmonary embolism. Can that detect lung cancer? Chest xray normal. 42 years old.

Yes,: that type of CT can detect lung cancer. Tiny nodules 2mm or less can potentially be detected. There are benign causes for nodules as well, so although CT is good at finding nodules, and possibly assigning a reasonable probability of malignancy based on certain imaging features, CT cannot make a definitive diagnosis of cancer. ...Read more
