Structural changes induced by antineoplastic therapies: keys to evaluate tumor response to treatment.

abstract：:Although dual-energy CT (DECT) may prove useful in a variety of abdominal imaging tasks, renal mass evaluation represents the area where this technology can be most impactful in abdominal imaging compared to routinely performed contrast-enhanced-only single-energy CT exams. DECT post-processing techniques, such as cre...
