Comprehensive radionuclide esophagogastrointestinal transit study: methodology, reference values, and initial clinical experience.

Unlabelled: A radionuclide methodology and reference values have been developed for a single gastrointestinal transit study including esophageal transit, liquid and solid gastric emptying, and small- and large-bowel transit, using (111)In-diethylenetriaminepentaacetic acid (DTPA) with the standardized (99m)Tc-labeled solid meal.

Methods: Eighteen healthy subjects and 18 patients were investigated. The esophageal transit study was performed with 3.

Value of imaging in head and neck tumors.

In this review, the value of imaging in the management of head and neck tumors is summarized. The many diverse tumors of the head and neck are grouped for purposes of staging and treatment. The groupings of malignancies consist of sinonasal, nasopharynx, salivary gland, oral cavity, oropharynx, hypopharynx, larynx, and thyroid tumors.

Follow-up or Surveillance (18)F-FDG PET/CT and Survival Outcome in Lung Cancer Patients.

Unlabelled: The value of performing follow-up PET/CT imaging more than 6 mo after the conclusion of therapy-either as a routine practice or because of clinically suspected recurrence-is not well established. The purpose of this study was to evaluate the added value of follow-up PET/CT to the clinical assessment and survival outcome of lung cancer patients.

Methods: This was a retrospective study of 261 biopsy-proven lung cancer patients at a single tertiary center.

Postoperative temporalis muscle atrophy and the use of electrocautery: a volumetric MRI comparison.

Postoperative temporalis muscle atrophy from injury to the neurovascular supply can cause significant cosmetic disfigurement, and avoidance of electrocautery use has become a common practice in minimizing this outcome. We attempted to quantify the effects of electrocautery on temporalis atrophy by retrospectively reviewing postoperative magnetic resonance images in patients having undergone an orbital frontal craniotomy. We reviewed medical records and compared volumetric measurements of the temporalis muscle in 25 patients using the contralateral temporalis muscle as an internal control.
