A 64-year-old man presented with clinical unilateral thyroiditis after chronic left neck trauma from his car seat belt. Thyroid function tests were normal. The initial thyroid Tc-99m pertechnetate scan demonstrated decreased uptake in the entire left lobe of the thyroid. The follow-up scan 1 month later showed a more normal uptake in the left lobe. This patient's clinical course, laboratory val...

  Tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of Meckel's diverticulum. Interpretation of Meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. The activity must be of the same pattern and intensity as gastric uptake. We present a 13-year-old patient with gastrointest...

 Parathyroid adenoma involving a single parathyroid gland is the underlying cause of 80-85% of primary hyperparathyroidism (PHPT). Skeletal system is significantly affected by PHPT. Brown tumors are known to have affinity for 99mTc-MIBI. We report a rare case of PHPT presenting with diffuse bony pain, high calcium level and significantly elevated alkaline phosphatase level. 99m<...

DMSA (meso-2,3-dimercaptosuccinic acid) adalah suatu senyawa dengan gugus sulfhydryl yang mampu berikatan secara chelation berbagai logam berat. Awalnya dimanfaatkan sebagai antidotum keracunan berat, namun seiring berjalannya ilmu pengetahuan, berhasil ditandai menggunakan Tc-99m Pertechnetate dan dimaanfaatkan luas dalam bidang kedokteran nuklir. scan telah digunakan nefrourologi, terutama un...

OBJECTIVE In the last decade, surgery of primary hyperparathyroidism (HPT) due to a solitary adenoma has moved on from the traditional wide bilateral neck exploration (BNE) to more limited approaches such as unilateral neck exploration and minimally invasive parathyroidectomy. DESIGN To define the role of intraoperative gamma probe and injection of a low (99m)Tc-MIBI dose in performing minima...

Tc-99m pertechnetate scintigraphy is a standard procedure for diagnosis of Meckel's diverticulum. It usually presents as a static abnormality in the midabdomen. We report a 17-year-old patient with severe lower gasterointestinal bleeding and anemia. On Tc-99m pertechnetate scintigraphy, focal abnormal activity was noted in the abdomen which was moving in the abdominal cavity. The patient underw...

A series of 253 consecutive patients with proved primary hyperparathyroidism due to parathyroid tumours was reviewed. There were 68 (26.9%) men and 185 (73.1%) women, with a median age of 57 years (range 13-82 years). All patients, prior to successful parathyroidectomy, underwent one or more preoperative localization procedures such as: neck ultrasonography (US) in 191 (75.5%), (201)Tl/(99m)Tc-...

A 37-year-old male with a persistent increased parathyroid hormone level, after subtotal thyroidectomy and parathyroidectomy, was referred for scintigraphic localization of a possible ectopic parathyroid adenoma. Tc-99m pertechnetate and Tc-99m MIBI scintigraphy were performed on separate days. There was marked uptake of both tracers in the mediastinum, which at surgery was confirmed to be an e...

Meckel's diverticulum is a common congenital disorder which may result in Gl bleeding. For definite diagnosis before surgery, radiographic procedures such as small intestine barium studies are not greatly successful; on the other hand Tc-99m-Pertechnetate imaging is a physiologic and noninvasive method with high sensitivity and specificity. In this report, three patients with rectorrhagia...
