As MRI threatens the use of bone scintigraphy for skeletal metastases and 18F-fluorodeoxyglucose positron emission tomography (18FDG-PET) emerges as the main focus in nuclear oncology, the future role of the gamma camera in cancer imaging appears unclear. However, there is a range of pre-existing conventional gamma camera techniques that have incremental benefit over CT and other structural ima...
UNLABELLED Localization of sentinel lymph nodes can be challenging if they are in difficult anatomic locations or near high radiotracer activity. The purpose of this study was to assess the value of intraoperative real-time imaging using a portable gamma-camera in conjunction with a conventional gamma-counting probe when it is difficult to localize the sentinel node. METHODS After (99m)Tc-nan...
UNLABELLED This study described and validated a new solid-state single-photon gamma-camera and compared it with a conventional-SPECT Anger camera. The compact new camera uses a unique method for localizing gamma-photon information with a bank of 9 solid-state detector columns with tungsten collimators that rotate independently. METHODS Several phantom studies were performed comparing the new ...
