Evaluation of thyroid uptake, by administration of small activities of radioactive iodine (I or I), is a well-defined procedure. Nowadays, nuclear medicine departments are using scintillation cameras coupled to pinhole collimators to perform such studies. On the other hand, gamma probes, which are normally used in radioguided surgical procedures, can technically be used for measuring the thyroi...

A scintillation camera and computer assembly is described whereby clinical and research scintigraphic data can be processed by a computer through a videotape transfer system. This assembly can provide a full computer capability to hospital clinics which are not equipped with a computer but still require convenient and rapid data analysis. Tomographic and anatomical marker data can also be acces...

OBJECTIVE This study compared the 123I thyroid uptake measurements obtained from a gamma camera fitted with a low-energy all-purpose (LEAP) collimator to those obtained from a thyroid uptake probe and gamma camera fitted with a pinhole (PH) collimator. METHODS Thirty-one patients (27 female and 4 male patients) were studied for comparison between a probe and a gamma camera fitted with LEAP co...

The Daily intrinsic flood uniformity test of a gamma camera is required to be performed before using the gamma camera to acquire patient images. It is meant to detect changes in the performance of a gamma camera system that may affect the interpretation of clinical studies adversely.

UNLABELLED Paraaortic sentinel node biopsy may be a challenging procedure because the sentinel nodes are located retroperitoneally in close proximity to vital structures. The purpose of this study was to describe and evaluate the value of preoperative SPECT/CT for lymphatic mapping, and a portable gamma-camera for intraoperative radioguidance, in patients with paraaortic sentinel nodes. METHO...

UNLABELLED Heart to mediastinum count ratio (H/M) has been commonly utilized as an indicator of myocardial I-123 MIBG uptake. However, normal ranges of H/M were markedly different among various gamma camera systems. The purpose of this study was to clarify whether scatter correction by two-window method standardizes H/M among various gamma camera systems. METHODS Scatter uncorrected and corre...

We conducted a randomised prospective comparison of the Compression Hip Screw(CHS) and gamma nail for internal fixation of 60 intertrochanteric femoral fractures in elderly patients. The gamma nail group showed shorter convalescence and earlier full weight-bearing. There were however no significant differences in the operative time, blood loss, stay in hospital' and patien's mobility at the fin...
