Radiation nephritis: 99mTc hydroxydiphosphonate bone scan, 99mTc dimercaptosuccinic acid renal scan, and 18F-FDG PET/CT findings

99mTC dimercaptosuccinic acid (DMSA) scan in urinary tract infection.

Usefulness of 99mTc-dimercaptosuccinic acid renal scan in the diagnosis and follow-up of acute tubulointerstitial nephritis in children

BACKGROUND Symptoms and signs of acute tubulointerstitial nephritis (ATIN) are nonspecific; therefore, renal biopsy is often necessary to clarify the diagnosis. The aim of this study was to evaluate the use of 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy in the diagnosis and follow-up of ATIN. METHODS We retrospectively reviewed the charts of five patients (nine renal units) with a media...

99mTc dimercaptosuccinic acid (DMSA) scan in patients with established radiological renal scarring.

The findings on 99mTc dimercaptosuccinic acid (DMSA) scans were examined in 54 patients aged 3 to 33 years in whom renal scarring had been diagnosed radiologically in childhood after urinary tract infection. There was no recent history of infection. Vesicoureteric reflux had been present in 48 patients and had stopped in 23 at the time of the DMSA scan. In six of the 72 radiologically scarred k...

Acute phase 99mTc-dimercaptosuccinic acid scan in infants with first episode of febrile urinary tract infection.

BACKGROUND 99mTc-dimercaptosuccinic acid (DMSA) scan is the golden standard for the diagnosis of acute pyelonephritis and renal scaring. We investigated the use of acute phase DMSA scan in infants presented promptly to the hospital because of the first episode of their febrile urinary tract infection (UTI). METHODS Ninety-eight infants with microbiologically confirmed first episode of febrile...

Distant subcutaneous recurrence of a parathyroid carcinoma: abnormal uptakes in the 99mTc-sestamibi scan and 18F-FDG PET/CT imaging

We report a rare case of distant subcutaneous parathyroid carcinoma recurrence. A 50-year-old woman was referred to our hospital because of sustained hypercalcemia despite surgical removal of a parathyroid carcinoma. A focal uptake in the upper mediastinal area was detected in a (99m)Tc-sestamibi scan, and (18)F-fluorodeoxyglucose (FDG) positron-emission tomography (PET)/computed tomography (CT...
