Exclusion of urolithiasis in the presence of contrast media using dual energy
 |
Case history: 45-year-old female with cholangiocellular carcinoma and known peritoneal carcinosis presents for follow-up scan post surgery and post chemotherapy. Question: Can virtual non-enhanced imaging confirm the presence of a small renal stone in the lower pole of the right kidney found incidentally? Read more
