Hepatic hemangiomas and malignant tumors: improved differentiation with heavily T2-weighted conventional spin-echo MR imaging.

abstract：:A survey of the members of the Society for Pediatric Radiology indicates that currently the majority of pediatric radiologists do not perform or interpret examinations using radionuclides, ultrasound, or computed tomography (CT). A decisive factor determining involvement with these techniques is the type of institutio...
