Evaluation of the Outcome of Pyeloplasty in Children with Poorly Functioning Kidneys due to Unilateral Ureteropelvic Junction Obstruction.

Aim: To analyze the outcome of upfront pyeloplasty in kidneys of children with unilateral ureteropelvic junction obstruction (UPJO).

Materials And Methods: Thirty-three consecutive cases with split renal function (SRF) of ≤20% on dynamic renal scintigraphy (DRS) underwent upfront pyeloplasty with a nephrostomy tube and trans-anastomotic stent. Outcome was analyzed based on symptomatic relief, nephrostomy output, surgical complications and changes noted in pre-and post-operative findings on renal ultrasound (US), and DRS.

Splenic Uptake in 99 mTc-Methylene Di-Phosphonate Scan in a Pediatric Patient with Acute Lymphocytic Leukemia.

An 12-year-old boy with relapse of acute lymphocytic leukemia and suspected skeletal involvement underwent mTc-Methylene Di-Phosphonate skeletal scintigraphy, which revealed a lytic "cold" lesion in the pelvis and diffuse splenic uptake. There was no active splenic infiltration in cross-sectional imaging. However, the patient had a history of multiple blood transfusions, which is a rare cause for diffuse splenic uptake.

Simultaneous Detection of Biliary Injury and Vascular Infarct using 99mTc-HIDA Scintigraphy in a Patient with Trauma.

A 45-year-old male with a history of trauma was referred to the department of nuclear medicine to identify site of a biliary leak, which could not be identified in ultrasound and exploratory laparotomy. Contrast-enhanced computed tomography (CT) was able to identify lacerations in the right lobe of the liver, but the extent of injury to the biliary pathways and vessels was unclear. 99mTc-HIDA scintigraphy with single-photon emission CT/CT was not only able to identify the site of leak but also the extent of infarcted area.

PET/computed tomography enterography.

Interpretation of gastrointestinal PET/computed tomography (PET/CT) is often complicated by anatomy including bowel folds, flexures, variant redundancy, decompressed bowel segments and physiological uptake. This makes it very difficult to identify both true positives and true negatives, compromising both sensitivity and specificity. CT enterography is increasingly being integrated into the field of nuclear medicine to address these issues.

Diagnostic Accuracy of Stress Myocardial Perfusion Imaging in Indian Diabetic Patients: A Single Centre Experience.

Unlabelled: Diabetics have around 2-4 times increased risk of coronary artery disease(CAD) and it is the most important cause of mortality in these patients. This study was carried out to compare the sensitivity, specificity and accuracy of MPI-SPECT among diabetics and non-diabetics in the Indian population.

Material And Methods: This retrospective study included 261 patients; 213 males and 48 females, with 75 diabetic and 186 non-diabetic patients.

Indirect evidence of intravesical ureterocele on (99m)Tc-diethylene triamine pentaacetic acid scan.

Ureterocele is a common ureteric anomaly detected in pediatric population. Ureterocele diagnosis and evaluation need a variety of radiological methods. We report a case of 5-year-old female child sent for (99m)Tc-diethylene triamine pentaacetic acid scan for evaluation of glomerular filtration rate and excretory function of kidneys in view of right-sided hydroureteronephrosis and pyonephrosis with percutaneous tube in situ.

Osteosclerotic and osteolytic manifestations of hyperparathyroidism in a case of Tc99m SestaMIBI positive parathyroid adenoma.

Primary hyperparathyroidism is the first differential diagnosis when a patient presents with asymptomatic hypercalcemia. The symptoms of hyperparathyroidism can be as grave as skeletal, cardiovascular, and neuropsychological changes. Skeletal manifestations are relatively common, and patient may present with generalized or focal bone pains, fragility fractures, subperiosteal bone resorption, and osteolytic lesions like brown tumors and salt and pepper appearance of the skull.

Radionuclide cisternography: A prudent investigation in diagnosing spontaneous intracranial hypotension.

Spontaneous intracranial hypotension (SIH) is a cause of new persistent headache, which disappears on recumbence and reappears in sitting/standing position (orthostatic headache). We present a case of orthostatic headache, where the patient was suspected to have SIH and was subjected to radionuclide cisternography (RNC) using 99m Technetium Diethylenetriaminepenta acetic acid for confirmation of diagnosis. After due consent from the patient, the radiotracer was injected intra-thecally and serial images were acquired until 24 h.

Tc99m MDP bone SPECT in a case of osteomyelitis of the skull.

A seven-year-old male child presented with swelling at the left temporal region. His skull X-ray was normal. A three-phase bone scan showed increased blood flow, soft tissue activity, and increased tracer concentration in the left temporal region.
