Bone scintigraphy can diagnose osteoporotic vertebral compression fractures better than conventional radiography.

Objective: Most difficult and very frequent complications of osteoporosis are vertebral compression fractures (VCF). Bone scintigraphy with Tc-phosphonates enables early detection of vertebral compression fractures in the first 72 hours of occuring. Typical scintigraphic findings is markedly increased radiotracer uptake in the linear pattern, throughout collapsed vertebral body.

Technetium-99m-dimercaptosuccinic acid renal scintigraphy can guide clinical management in congenital hydronephrosis.

Objective: The purpose of this study was to evaluate damage of the kidney with technetium-99m-dimercaptosuccinic acid (Tc-DMSA) scintigraphy in children with congenital hydronephrosis (CH) and the influence of other postnatal associated diagnoses on abnormal Tc-DMSA findings.

Subjects And Methods: Tc-DMSA scintigraphy in 54 children (17 girls and 37 boys), aged from 2 months to 5 years (median 11 months) with 66 congenital hydronephrotic renal units (RU) (42 unilateral hydronephrosis-29 boys and 13 girls; 12 bilateral hydronephrosis-8 boys and 4 girls) was performed. Male/female ratio was 2,2:1, unilateral/bilateral hydronephrosis ratio was 4:1.

Positive Tc-MIBI and the subtraction parathyroid scan are related to intact parathyroid hormone but not to total plasma calcium in primary hyperparathyroidism.

Objective: Primary hyperparathyroidism (pHPT) is characterised by increased parathyroid hormone (PTH) secretion and consequently increased plasma calcium. During the last few decades parathyroid scintigraphy (PS), is applied in almost all patients with pPHT before surgery and specifically before minimally invasive parathyroidectomy. The aim of this study was to find the best cut-off levels of total plasma calcium and intact PTH (iPTH) that correlate with positive technetium-99m-methoxy isobutyl isonitrile (Tc-MIBI) PS and with positive subtraction PS (SPS) in patients with pHPT and thus the positive diagnostic value of these PS.

Estimated Dose to Family Members of Patients Treated with Radioiodine.

Patients who receive therapeutic amount of 131I are potentially significant source of radiation to their family members and general public. The aim of this study was to estimate effective dose to family members of patients treated with radioiodine, released after 3 d of hospitalization and to compare with dose constraints proposed by international recommendations. The thermoluminescence dosemeters (TLD 100) and Radiation Dose Assessment Resource (RADAR) software were used for assessment of effective doses to 60 family members of the same number of hyperthyroid and thyroid carcinoma patients.

Evaluation of diagnostic parameters from parotid and submandibular dynamic salivary glands scintigraphy and unstimulated sialometry in Sjögren's syndrome.

Our aim was to validate eight scintigraphic salivary gland (SG) parameters, as diagnostic parameters in patients with Sjögren's syndrome (SS). We used the standardized stimulated dynamic salivary gland scintigraphy (DSGS) protocol and correlated this with the unstimulated whole sialometry (UWS) functions. The DSGS and UWS tests meeting the European and the USA diagnostic classification criteria for SS were applied in twenty patients and in ten normal controls.

Correlation of subtraction parathyroid scintigraphy with weight, pathohistologic finding and oxyphil cell content of parathyroid glands in parathyroid hyperplasia.

Background/aim: Parathyroid hyperplasia (PHP) is defined as an absolute increase in the mass of parenchymal cells of the parathyroid gland. PHP is classified as primary, secondary and tertiary. The enlargement of parathyroid glands (PG) is usually asymmetric, resulting in a "dominant" gland.

Validity of dual tracer 99mTc-tetrofosmin and 99mTc-pertechnetate subtraction parathyroid scintigraphy in patients with primary and secondary hyperparathyroidism.

Background/aim: Primary hyperparathyroidism (pHPT) is an endocrine disease with the third highest incidence of all endocrine disorders after diabetes mellitus and hyperthyroidism. pHPT is typically caused by a solitary parathyroid adenoma, less frequently by multiple parathyroid gland disease (MGD) and rarely by parathyroid carcinoma. Secondary hyperparatyroidism (sHPT) is a common complication in patients with chronic renal failure.

Estimation of 99mTc-ciprofloxacin accumulation indexes in bone and joint bacterial infections.

Background/aim: 99mTc-ciprofloxacin is a radiopharmaceutical preparation sintetized to improve diagnostic accuracy of bacterial infections in human tissues. It is mostly applied in diagnosis of bone and joint infections. Many papers have confirmed its sensitivity to infection, but newer papers argued its specificity.

Renal scintigraphy in infants with antenatally diagnosed renal pelvis dilatation.

Background/aim: Ureteropelvic junction obstruction and vesicoureteral reflux are the most frequent entities identified on the basis of antenatal hydronephrosis. The aim of this study was to determine the incidence and pattern of abnormal renal scintigraphy findings in postnatal investigation of children with antenatal hydronephrosis.

Methods: Twenty-four infants (19 boys and five girls) presented with antenatal hydronephrosis and mild to moderate hydronephrosis on ultrasound in newborn period were referred for renal scintigraphy.

[Diagnostic validity of dynamic salivary gland scintigraphy with ascorbic acid stimulation in patients with Sjögren's syndrome: comparation with unstimulated whole sialometry].

Background/aim: Beside many actual groups of classification criteria, uniform classification criteria for Sjögren's syndrome (SS) are still missing. The ophtalmic component of SS is well defined. Criteria for classifying its oral component remain controversial.

[Incidence and imaging characteristics of skeletal metastases detected by bone scintigraphy in lung cancer patients].

Background/aim: Detection of metastatic bone disease by skeletal scintigraphy is a classical application of nuclear medicine in cancer patients. Detection of bone metastases in patients with lung cancer is necessary for an appropriate treatment modality. The aim of this study was to report the frequency and imaging characteristics of bone metastases detected by bone scintigraphy (BS) using technetium-99m phosphonates in patients with lung cancer.
