Pancreatic cancer often evades detection on CT scans due to its location deep within the abdomen and its resemblance to surrounding organs. This can lead to false negatives, where the cancer is missed and goes undiagnosed. The reported rate of missed pancreatic cancer on CT scans varies, but studies suggest that it can range from … Read more

In pancreatic imaging, “pancreas enhances homogeneously” refers to a uniform enhancement of the entire pancreas on a contrast-enhanced CT or MRI scan. This is typically a normal finding, indicating a healthy pancreas. In contrast, heterogeneous enhancement, where portions of the pancreas enhance differently, may be indicative of underlying conditions such as pancreatitis, tumors, or other … Read more

Liver metastases ultrasound is an imaging technique that uses sound waves to create images of the liver and detect the presence of metastatic lesions.
