Renal Metastasis and Dual (F-Fluorodeoxyglucose and I) Avid Skeletal Metastasis in a Patient with Papillary Thyroid Cancer.

Differentiated thyroid carcinoma (DTC) though usually behaves in an indolent manner, can have unusual metastatic presentation. Initial presentation of metastatic disease has been reported in 1-12% of DTC being less frequent in papillary (~2%) than in follicular (~10%) thyroid carcinoma. Renal metastasis from DTC is very rare.

Brain perfusion single photon emission computed tomography abnormalities in patients with minimal hepatic encephalopathy.

Background: Minimal hepatic encephalopathy (MHE) is the mildest form of hepatic encephalopathy (HE). Minimal hepatic encephalopathy patients do not demonstrate clinically overt symptoms of HE but present with abnormal neuropsychological and/or neurophysiological tests indicative of cerebral dysfunction. This study was performed in such patients to identify regions of abnormal cerebral perfusion and to correlate regional cerebral blood flow (rCBF) changes with psychometric hepatic encephalopathy score (PHES), Child-Turcotte-Pugh's score (CTP), and model for end-stage liver disease (MELD) score.

Tc99m-ECD brain SPECT in patients with Moyamoya disease: A reflection of cerebral perfusion status at tissue level in the disease process.

Background: Moyamoya disease is a rare, progressive cerebrovascular disorder caused by intracranial stenosis of the circle of Willis, resulting in successive ischemic events. Computed tomography (CT) and magnetic resonance imaging (MRI) play a major role in diagnosis.

Objective: The aim of the study was to describe the spectrum of findings on brain SPECT in patients with Moyamoya disease and to compare the findings with other investigations.

Role of Tc99m sulfur colloid scintigraphy in differentiating non-cirrhotic portal fibrosis from cirrhosis liver.

Background: Two most important causes of portal hypertension are cirrhosis of liver and non-cirrhotic portal fibrosis (NCPF). The purpose of this study was to assess the scintigraphic appearances of Tc99m sulfur colloid liver scan in differentiating liver cirrhosis from NCPF.

Materials And Methods: Retrospective analysis records of 146 patients (91 male and 55 female) with diffuse hepatocellular disease was done for liver size, liver uptake, spleen size, spleen uptake, colloid shift to bone marrow and lungs.

Pertechnetate SPECT-CT in corrosive gastric injury.

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.

Utility of Iodine-131 hybrid SPECT-CT fusion imaging before high-dose radioiodine therapy in papillary thyroid carcinoma.

The management protocol for differentiated thyroid cancer includes whole body iodine-131 imaging, to detect residual thyroid tissue and distant metastasis, after thyroidectomy. However, the diagnostic dose of radioiodine may fail to detect the non-functioning or poorly functioning metastasis. We present a case where hybrid single photon-emission computed tomographic and computed tomographic (SPECT-CT) fusion imaging, using a diagnostic dose of iodine-131, was able to detect both functioning as well as non-functioning pulmonary metastases, prior to high-dose radioiodine therapy.

Diagnosis and prognostic significance of minimal hepatic encephalopathy in patients with cirrhosis of liver.

Background And Aims: Minimal hepatic encephalopathy is the mildest form of the spectrum of hepatic encephalopathy (HE) that impairs health-related quality of life. We assessed (1) the usefulness of psychometric hepatic encephalopathy score and critical flicker frequency for the diagnosis of minimal hepatic encephalopathy, and (2) prognostic significance of minimal hepatic encephalopathy.

Methods: One hundred patients with liver cirrhosis without overt HE were subjected to psychometric hepatic encephalopathy score and critical flicker frequency evaluation.

Potential diagnostic role of renal scintigraphy in the management of patients with high anorectal malformation.

Urological problems are the leading associated anomalies in patients with anorectal malformation (ARM). In this study, we evaluated the role of scintigraphy in managing patients with high ARM. The records of infants with urologic anomalies on abdominal ultrasound and referred for scintigraphic evaluation were retrospectively analyzed.
