HBG2 and teratoma: T1WI in-phase (IP) and out-of-phase (OOP) imaging are very useful for the fat-containing lesions and to identify the disease states related to the presence of diffuse or focal steatosis in the liver, pancreas, adrenal glands, etc. Pancreatic lesions like teratoma have high signal intensity on T1WI and T2WI TSE (turbo spin-echo) images similar to that of subcutaneous fat.[7] Some hemorrhagic lesions (containing methemoglobin) will also demonstrate similar imaging features.
