Can a tumour in the pancreas be seen on a non contrast CT scan?

Can a tumour in the pancreas be seen on a non contrast CT scan?

A CT scan with oral: ... and IV contrast is what I would choose if I wanted to check for the presence of pancreatic tumor. The pancreas can be hard to visualize on a non-contrast study. However, fat in the abdomen can help delineate it in some patients. An abdominal ultrasound can help determine if a mass is cystic. Whether a mass is visible will also depend on its size and location. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

How is a 5mm non-calcified lower lobe pulmonary nodule in a non-smoker managed? Was found incidentally on a contrast CT of abdomen.

How is a 5mm non-calcified lower lobe pulmonary nodule in  a non-smoker managed? Was  found incidentally on a contrast CT of abdomen.

Recommendation: Fleischner society recommendation for nodule this size is follow up ct at 12 months and, if no change, no further follow up for low risk(e.g. Nonsmoker etc..) patient. For high risk patient, follow up CT at 6-12 months and then at 18-24 months if no change. ...Read more

Would a radiologist identify multiple 3.4 cm size lung lesions on the outer part of the lung on a chest xray??

Would a radiologist identify multiple 3.4 cm size lung lesions on the outer part of the lung on a chest xray??

Lung nodules/lesions: normally abnormalities larger than 1 cm and sometimes even smaller than 1 cm will be noted by a radiologist interpreting a chest x-ray. Normal structures are not typically mentioned. It's also possible to have lesions visible on a CT scan that won't be visible on a plain chest x-ray either due to size or location possibly hidden by other structures such as the heart, diaphragm, or ribs. ...Read more

Had a CT abdominal & pelvic scan found a 7 mm lung spot on the lower left lung. Radiologist wants a CT lung scan done. Thoughts?

Had a CT abdominal & pelvic scan found a 7 mm lung spot on the lower left lung. Radiologist wants a CT lung scan done. Thoughts?

Get it done: The ct will show if you have other nodules or evidence of previous infection, such as histoplasmosis, that commonly cause nodules. After that your doctor can know if you need any further procedure or followup. Don't worry too much, these nodules are common and mostly benign. ...Read more

I have a renal ultrasound in 2 weeks. Radiologist noted hydronephrosis on my CT scan from 12/26. Will this study confirm the CT result?

I have a renal ultrasound in 2 weeks. Radiologist noted hydronephrosis on my CT scan from 12/26. Will this study confirm the CT result?

Yes: Ct likely done for pain, possibly for a kidney stone which may or may not have passed. Us will show if hydronephrosis has resolved. This would be good management. Us not necessary to confirm ct diagnosed hydronephrosis if due to non-calculus (stone) obstruction like at upper ureter. Such obstruction would require a mag3 nuclear scan to quantify obstruction and need for possible corrective surgery. ...Read more

Would calcified pleural plaques look the same as melanoma metastasis on a regular CT scan?

Would calcified pleural plaques look the same as melanoma metastasis on a regular CT scan?

No, they would: not look alike. Calcified plaques are very dense, melanoma density is often greater than normal soft tissue, but far below calcium. ...Read more

Had a CT scan and showed a large bullous lesion on left lung how can this be treated?

Wow: This is a tough issue. It will need the discussion of several lung specialists to find the right option. Vats bullectomy and watchful waiting with bronchodilators are options. Stay away from er, they tend to put in chest tubes because they think this is a pneumothorax. In asymptomatic patients it is best to not perform surgery. You must see a lung doc. ...Read more

I have stage 2b prostate cancer and a small low dense lesiion was found in the dome of my liver during ct scan with contrast. Could this mean Metases?

I have stage 2b prostate cancer and a small low dense lesiion was found in the dome of my liver during ct scan with contrast. Could this mean Metases?

Slight possibility: A metastasis to the liver in your situation is very unlikely. However, "Never say always or never". It should be followed up with other studies to make sure it is not a metastasis. There is also the possibility that it is caused by a condition other than the prostate cancer. Have you been treated for the primary prostate cancer? ...Read more

I have a 5mm hypodense lesion on spleen, detected by non contrast CT scan. Potential causes and next steps?

I have a 5mm hypodense lesion on spleen, detected by non contrast CT scan. Potential causes and next steps?

The vast majority: of incidentally discovered splenic lesions like this are benign cysts, pseudocysts, or hemangiomas requiring no treatment. Further evaluation with ultrasound or contrast enhanced CT or MRI may be useful for a more confident characterization of the lesion. Talk to your doc about it. ...Read more

Can multiple lung lesions 3.2 CM in size be detected on a chest X-ray of the lungs?

Can multiple lung lesions 3.2 CM in size be detected on a chest X-ray of the lungs?

Yes: The resolution of the cxr is that it can detect nodules as small as 1cm or even smaller depending on the location, i.e., not hidden by the bones or the heart but a 3.2 cm size nodule should definitely be seen. ...Read more

Could good quality images of a cta chest detect also detect lung nodules and coronary problems present in the thorax? They detected a liver angioma on mine for example, incidentally ...

Yes: While CT angiogram of the chest won't provide a numeric score for coronary calcium, the radiologist can say whether there is coronary calcification, whether there is more than expected. Lung nodules will definitely be seen on a CT angiogram of the chest. ...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
