Purpose: To evaluate the diagnostic accuracy of 131I-6β-iodomethyl-19-norcholesterol (NP-59) adrenal scintigraphy for subtyping diagnosis primary aldosteronism (PA), considering as gold standard unilateral PA (UPA), either results venous sampling (AVS) or outcome after adrenalectomy. Methods: A retrospective multicenter study was performed on patients from 14 Spanish tertiary hospitals who unde...

Purpose: To compare the effects of gallium-67 (Ga-67) scintigraphy with computerized tomography (CT) scanning in the diagnosis of head and neck neoplasm. Materials and Methods: Eighty-three patients with neoplasm in head and neck underwent local CT scanning and Ga-67 scintigraphy preoperatively. The results were verified pathologically after operation. Results: In total 43 cases of benign neopl...

UNLABELLED Somatostatin receptor scintigraphy (SRS) has been shown to reveal sarcoidosis sites. The aim of this study was to prospectively compare SRS and gallium scintigraphy in the evaluation of pulmonary and extrapulmonary involvement in patients with proven sarcoidosis. METHODS Eighteen patients with biopsy-proven sarcoidosis were included. Nine were or recently had been receiving steroid...

BACKGROUND Quantitative evaluation of pulmonary perfusion using lung perfusion scintigraphy in patients with atriopulmonary anastomosis (APA) or total cavopulmonary connection (TCPC) or partial cavopulmonary connection (PCPC) is difficult because of preferential draining of the venae cavae to one lung. Scintigraphy is the gold standard. Phase-velocity MRI (PV-MRI) is a new technique for determi...

BACKGROUND Current breath tests for measurement of gastric emptying of solids are expensive, possibly inaccurate, and require cumbersome calculations. AIMS We wished to validate a simplified solid gastric emptying test using a [(13)C]Spirulina platensis breath test for accurate results relative to scintigraphy. SUBJECTS Thirty healthy volunteers. METHODS We measured gastric emptying of eg...

Introduction: In Islamic countries in the month of Holy Ramadan many Muslims based on their religious Legislation refuse fluid intake during the fasting time though instructed to drink after injection of Tc-99m Methylene-diphosphonates [Tc-99m MDP] used for skeletal scintigraphy. We aimed to establish whether fluid restriction in Tc-99m MDP skeletal scintigraphy has an impact on its quality. M...

The features of Hypertrophic pulmunary osteoarthropathy (HPOA) on radionuclide bone scintigraphy have been well described in case reports and small series of patients. The aim of this study was to investigate prospectively the prevalence and distribution of HPOA in a large series of patients with carcinoma of the lung. Two hundred and eleven patients aged 31-89 years (average age 66 years...

Background: It is pertinent to objectively assess the severity of diabetic gastroparesis and tailor treatment accordingly. The current study was planned to document gastroparesis by gastric emptying scintigraphy (GES) objectively and see the effect of medications and diet control on clinical and GES after four weeks. Methods: A prospective, open-label randomized trial was conducted in the Depa...

AIM To evaluate the feasibility of V/Q SPECT and analyze its contribution to planar V/Q lung scintigraphy in the diagnosis of pulmonary embolism (PE). MATERIAL AND METHODS A total of 109 patients with suspected PE showing Wells score>2 and elevated D-dimer were studied. The V/Q could not be completed in 7 patients, so they were excluded. Ventilation and perfusion scans were done using Techneg...

UNLABELLED In metastatic breast cancer, the estrogen receptor (ER) is a well-known prognostic factor predictive of response to hormonal treatment in most, but not all, patients. Recently, a receptor-specific radioligand for in vivo imaging of the ER in breast cancer patients was developed: (123)I-labeled cis-11beta-methoxy-17alpha-iodovinyl-estradiol (Z-(123)I-MIVE). It showed high sensitivity ...
