Study suggests ways to cut CR radiation

A new study by Australian researchers has found that the radiation dose delivered in computed radiography (CR) examinations could be cut in half by adjusting the manufacturers recommended range (MRR) for exposure indices (EIs) by as little as 10%.

MR proves accurate and comfortable for colon imaging

Dr. Jörg Debatin from the University Hospital Essen in Germany said the two most important qualities of any screening test are diagnostic accuracy and patient acceptance -- requirements that MR colonography appears to fulfill. The procedure has been shown to be accurate for the detection of clinically relevant colonic polyps larger than 10 mm.

Ultrasound has unique strengths in breast imaging

The primary role of ultrasound in breast imaging is to differentiate cystic from solid lesions. The modality can also be used to confirm a suspected or palpable mass, as an aid to treatment planning, and for needle guidance in interventional procedures. Dr. Debra Ikeda from Stanford University offers tips for performing breast ultrasound.

Tamoxifen confuses uterine appearance on ultrasound

The unusual ultrasound appearance of the uterus in women receiving tamoxifen citrate can be misinterpreted as endometrial thickening. This confusing appearance is due to microcystic change in the proximal myometrium of the uterus, according to a presentation at the 2001 International Society of Ultrasound in Obstetrics and Gynecology world congress in Melbourne, Australia.

Two cases of pathologically confirmed intrahepatic cholangiocarcinomas in 68-year-old male patients. In both cases (A-H, case 1; I-P, case 2), CT scans (B, F, case 1; J, N, case 2) revealed intrahepatic bile duct dilation and suspected nodular lesions. While F-18 FDG PET/CT (A, C, D, case 1; I, K, L, case 2) failed to demonstrate abnormal tracer uptake (SUVmax 3.5, TBR 1.3 in Case 1; SUVmax 2.6, TBR 1.2 in Case 2), F-18 FAPI-04 PET/CT (E, G, H, case 1; M, O, P, case 2 ) showed positive uptake in the nodular lesions (SUVmax 9.7, TBR 3.5 in Case 1; SUVmax 9.6, TBR 3.3 in Case 2).
