Tc99m Diphosphonate imaging: Giant cell tumours on MDP scanning

Imaging Islet Cell Tumours

Islet cell tumours are rare lesions. The majority (85%) are functioning hormone-producing tumours, insulinomas and gastrinomas being the most common. Approximately 15% of islet cell tumours are nonfunctioning. These are usually larger lesions, often presenting at an advanced stage as a pancreatic mass or with metastatic disease. This review will focus on the role of endoscopic ultrasound in the...

Does I-131-MIBG underestimate skeletal disease burden in neuroblastoma?

BACKGROUND Controversy persists as to the need for both MIBG and bone scanning in routine evaluation of neuroblastoma. AIM To compare the efficacy of I-131- metaiodobenzylguanidine (MIBG) scan against that of conventional Tc99m- methylene diphosphonate (MDP) bone scan for the detection of skeletal deposition of neuroblastoma. METHODS AND MATERIAL The study included 57 patients (36 boys, 21 ...

Evaluation of Guided Tissue Regeneration Following Third Molar Extraction by Bone Scintigraphy Using Tc99m-MDP

Extraction of impacted third molars is a well-established and documented procedure. Guided tissue regeneration can be used to aid in wound healing and increase osseous tissue formation. To assess the regenerative treatment outcome, several variables are routinely used; these include primarily histology and direct measurement of bone. Other proxy measurements, such as radiographic analysis, clin...
