Since its release for routine clinical use, (99m)Tc-mercaptoacetyltriglycine (MAG3) has become an important alternative to (131)I-labeled orthoiodohippuran. The cold kit for MAG3 is expensive, especially in developing countries. Therefore, unique storage conditions should be provided for cost reduction. Cold fractioning is a well-known procedure but has special requirements, such as a nitrogen ...

Scintigraphy with Tc-99m dimercaptosuccinic acid (DMSA) is considered a reference method for assessment of parenchymal lesions and estimation of differential kidney function. The aim of study was to evaluate Tc-99m mercaptoacetyltriglycine (MAG3) dynamic renal scintigraphy for the same purpose. 188 patients, submitted to both studies within three months, were divided in two groups. In the first...

A 71-year-old man with newly diagnosed hypertension was referred for Technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) renal scintigraphy to evaluate the recent onset of impairment in renal functions. Dynamic imaging revealed activity flow which was suspicious for aortic aneurysm (AA) with a concurrent decrease in left renal blood flow. CT angiography of the thoracoabdominal aorta confirmed...

We have developed an automated system for the preparation of highly concentrated 188Re-perrhenate, diethylenetriamine pentaacetic acid (DTPA) and mercaptoacetyltriglycine (MAG3). The three procedural steps include concentration of 188Re-perrhanerate, chelation and purification and sterilization. The steps are operated by a small micro-controller. The eluted 188Re-perrhenate of 15 GBq/18 ml from...

A 22-year-old female patient with severe hypertension underwent both Technetium-99m diethylenetriaminepentaacetate and Technetium-99m mercaptoacetyltriglycine basal and captopril renal scintigraphy. While no significant change was seen with Tc-99m DTPA, there was left sided parenchymal retention of captopril Tc-99m MAG3 suggesting renal artery stenosis which was confirmed by angiography.

Background: Diuretic renography using 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) is a relatively non-invasive technique and has been increasingly used as reliable for the evaluation of kidney function in wide range disorders. Methods: In this retrospective study, we retrieved medical records patients referred to Radiology Department Radiology, King Abdulaziz Specialist Hospital, Taif, Saudi Ar...

Background: Screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (APN). Diuretic Tc-99m mercaptoacetyltriglycine (MAG3) scintigraphy with zero time injection of furosemide (MAG3-F0) was observed to display focal parenchymal disorders. The advantages of MAG3 include: lower radiation dose and short duration of the test. The aim of this study was to...

We quantitatively evaluated total and individual renal function by technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) renal scintigraphy before and after radiofrequency ablation (RFA) of renal tumors. Eleven patients who underwent Tc-99m MAG3 renal scintigraphy 1 week before and after RFA were evaluated (7 men and 4 women; age range: 23-83 years; mean age: 60.6 years). Five patients had soli...

Üreteropelvik bileşke darlığı (UPD), tanısı ile izlenen çocuk hastaların yönetimi tartışmalıdır ve merkezlere göre değişkenlik gösterir. Bu çalışmada Pamukkale Üniversitesi Çocuk Nefroloji Kliniğinde UPD tanısıyla takip edilen başvuru izlem bulgularının değerlendirilmesi amaçlanmıştır. kliniğinde Ocak 2014 Ağustos 2021 tarihleri arasında verileri retrospektif olarak değerlendirildi. Hastaların ...
