Do CT scans always show cancer?
Can a CT scan detect cancer? A CT scan, like any imaging tool, cannot detect cancer, though it may be useful in helping to identify a mass and determine its location and size.
What cancers does a CT scan not detect?
Where MRI really excels is showing certain diseases that a CT scan cannot detect. Some cancers, such as prostate cancer, uterine cancer, and certain liver cancers, are pretty much invisible or very hard to detect on a CT scan. Metastases to the bone and brain also show up better on an MRI.
Can you still have cancer with normal blood work?
New research suggests that a routine blood test could help find cancers early. Researchers have previously shown that high levels of platelets – cells in the blood that help stop bleeding – can be a sign of cancer. But now they have found that even slightly raised levels of platelets may be an indication of cancer.
What is a CT scan looking for?
CT scans can detect bone and joint problems, like complex bone fractures and tumors.

Can a radiologist tell if it is cancer?
While even the most advanced imaging technology doesn’t allow radiologists to identify cancer with certainty, it does give them some strong clues about what deserves a closer look. Today we’ll discuss a few things that radiologists are on the lookout for when examining mammography and breast ultrasound images.
Can a CT scan show stomach problems?

Can colon polyps be seen on CT scan?
Polyps are diagnosed by either looking at the colon lining directly (colonoscopy) or by a specialized CT scan called CT colography (also called a virtual colonoscopy).
What are the disadvantages of a CT scan?
In general, a CT scan has the advantage of short study time (15 to 20 minutes) with high quality images. However, disadvantages include the need for ra- diation exposure and the use of a contrast material (dye) in most cases, which may make it inappropriate for patients with significant kidney problems.
What tests are done to check for cancer?
Imaging tests used in diagnosing cancer may include a computerized tomography (CT) scan, bone scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, ultrasound and X-ray, among others. Biopsy. During a biopsy, your doctor collects a sample of cells for testing in the laboratory.
