The effect of glucagon on FDG uptake in skeletal muscle.

Glucagon is used as an anti-motility agent during gastrointestinal tract examinations. We experienced subjects with enhanced 18F-fluorodeoxyglucose (FDG) uptake in whole-body skeletal muscle when conducting positron emission tomography (PET). The subjects had been administered glucagon during gastroscopy just prior to PET.

[Acute urinary retention secondary to aseptic meningoencephalitis in an infant--case report].

We report the case of a 21-month-old boy with urinary retention secondary to aseptic meningitis. After high fever for 10 days, appetite loss, somnolence, acute transient urinary retention, constipation and mild dysesthesia in bilateral lower limbs developed. Brisk reflexes were present in the lower extremities along with a positive Babinski reflex.

Usefulness of early-phase helical CT for detecting recurrent rectal cancer.

Purpose: To evaluate the usefulness of dynamic enhancement of helical CT in the detection of local recurrence of resected rectal cancer.

Materials And Methods: In 142 patients with a history of curatively resected T2 or T3 rectal cancer, follow-up plain CT indicated that they had a loco-regional recurrent tumor; consequently, they underwent follow-up pelvic helical CT providing accurate early-phase contrast enhancement in the lower pelvic region. The patients were divided into four groups according to the grade of contrast enhancement of the suspected mass-like lesion before and after contrast enhancement, and the correlation between groups and results obtained by biopsy and/or surgery were assessed.

[The diagnostic imagings of liver metastases].

The liver is an organ susceptible metastases. Malignant neoplasms of many organs frequently metastasize to the liver, particularly colon malignancies. Most metastases enter the liver via the blood circulation, but metastases through lymphatic vessels and the peritoneum are also common.
