RENAL, PELVIC AND MESENTERIC TUMORS WITH LOW SIGNAL INTENSITY ON T2-WEIGHTED MR IMAGE: A REVIEW

The magnetic resonance (MR) imaging of intra-abdominal tumors is necessary for clinical practice. MR imaging involves the optimal evaluation of masses due to its inherent soft tissue contrast and multiplanar scanning abilities. T2 low-signal tumors are not common, and individuals need to be careful when interpreting them. The tumors that contain smooth muscle components, a high nucleus-to-cytoplasm ratio, or papillary architecture, among other components, tend to display low signal intensity on T2-weighted images. MR imaging allows for both the detection and characterization of tumors, especially when they have low signal intensity when presented on T2-weighted images. As a result, it becomes essential to identify the various characteristics that define each tumor. Identification of the tumor spectrum and knowing the cause of low signal intensity on T2 –weighted images helps the radiologist to narrow the differential diagnosis and reach a final diagnosis.
