background: local ablative treatments play an important role for patients who cannot be treated surgically. radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. microwave ablation (mwa) is a new minimally invasive treatment promising several improvements. the aim of this retrospective study was to evaluate the eff...

We report a 24-year-old woman with corrosive poisoning who was subjected to pertechnetate scintigraphy to evaluate gastric injury. Fusion imaging (SPECT-CT) provided valuable information regarding viability of gastric mucosa, and it helped guide appropriate management.

Gastrointestinal duplication cysts are a rare congenital malformation in the gastrointestinal tract, most commonly seen ilium. The present study reported child with mid ileal cyst ofthe ectopic gastric mucosa that was diagnosed by Technetium-99m pertechnetate single-photon emission computed tomography-computed tomography (SPECT-CT) scintigraphy. can massive lower bleeding early childhood (Mecke...

introduction: to retrospectively analyze the outcome of patients who underwent meckel’s scan in a local centre in hong kong over the past fifteen years. diagnostic values in different referring indications were also reviewed. methods: all patients who referred for meckel’s scan in a local hospital in hong kong from 1/1/1996 to 31/12/2010 were identified. patients’ demographic data, presenting s...

In primary hyperparathyroidism (pHPT), parathyroidectomy is the treatment of choice, but anatomic variations of ectopic glands may cause surgical failure. Reliable preoperative noninvasive localization procedures would have a positive impact on the operative time and increase recovery rate. We retrospectively evaluated 186 patients with pHPT who were studied before successful parathyroidectomy ...

Introduction: In this study the automatic separation of oral and salivary gland activity and spontaneous secretion by means of factor analysis for quantitative salivary gland scintigraphy is introduced. Methods: After intravenous administration of 99mTc sodium pertechnetate, dynamic scintigraphy was performed. 20 minutes after tracer application 2 ml of lemon juice was delivered to stimulate t...

  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...

Follicular thyroid carcinoma is common in regions with insufficient iodine diets and represents approximately 10-20 % of all thyroid malignancies1,2. The treatment of patients suffering from follicular thyroid carcinoma includes surgery and radioiodine therapy3. Although after definitive therapy, the survival of these patients is good, these patients need to be followed for local recurrences an...

We analyze the case of a patient with intermittent episodes of lower gastrointestinal bleeding and suspected Meckel's diverticulum, whose presence was confirmed by (99m)Tc-pertechnetate scintigraphy. A previous exploratory laparotomy had been performed without finding the diverticulum. In spite of years of medical treatment, the patient presented a new episode of lower gastrointestinal bleeding...

Scintigraphy of the salivary glands with technetium-sodium pertechnetate (99mTc) was undertaken on 320 patients with oral dryness or connective tissue disease using a computer assisted method that gave quantitative results about the major salivary gland function. Compared with clinical and histological data, scintigraphy provides a sensitive method, even though it is not specific, for detecting...
