TL;DR: The integration of the LCMRGIc study into the clinical workup of patients with partial epilepsy that are candidates for surgical resection of their epileptogenic focus and the potential to aid in improving the approach to medical therapy are resulted.

TL;DR: A list of nonneoplastic extraosseous conditions with demonstrated affinity for 99m Tc phosphates, derived from a literature search and the author's experience, is presented and mechanisms of localization of these agents are discussed.

TL;DR: The efficacy of using the 18F-fluoro-deoxyglucose (18F-DG) for measuring regional cerebral glucose utilization in man during functional activation is demonstrated and the technique is capable of providing functional maps in vivo in the human brain.

TL;DR: Administration of phenobarbital in a dose of 5 mg/kg/day for at least 5 days prior to the examination enhances and accelerates biliary excretion of IDA compounds and thereby significantly increases the accuracy of 99mTc-IDA scintigraphy in differentiating extrahepatic biliary atresia from neonatal hepatitis.

TL;DR: Conventional radionuclide renography has been modified to include a pharmacologic intervention by administration of intravenous furosemide in patients with hydroureteronephrosis to distinguish dilated, nonobstructed systems from those with significant mechanical obstruction.

TL;DR: The uptake of iodocholesterol correlates significantly with the abnormal secretion of cortisol in Cushing's syndrome, aldosterone in the model of adrenal zona glomerulosa function, and adrenal androgen secretion in hyperandorgenism.

TL;DR: The ability of the salivary gland image to detect and categorize mass lesions, which result in focal areas of diminished activity such as tumors, cysts, and most other masses, is disappointing, while its ability to detectand categorize Warthin's tumor, which concentrates pertechnetate, is much more valuable, although not specific.

TL;DR: The use of accelerator-produced radionuclides is undergoing a rapid if not exponential increase worldwide as mentioned in this paper, and the positron emitters are enjoying ever increasing attention and are being actively utilized in clinical research.

TL;DR: Patients presenting with an acute scrotum can dramatically reduce the number of surgical explorations for acute epididymitis and the techniques, clinical utility, and relationship to radionuclide imaging of Doppler ultrasound and gray scale ultrasound scanning are reviewed.

TL;DR: Two classes of radiopharmaceuticals may be used for imaging tumors of the musculoskeletal system, and soft tissue or tumor specific agents such as gallium-67, bleomycin, and radionuclide-labeled antibodies, which may be useful for detecting and localizing these tumors.

TL;DR: The results obtained provide accurate evidence of the migration of 99mTc-HAM from the vagina, through the uterus and tubes, to the peritoneal cavity and ovaries, and show that HERS is a simple noninvasive method for functionally imaging and assessing the patency of the female reproductive system pathways.

TL;DR: The two studies are complementary and together provide an effective means of evaluating the nasolacrimal drainage system.

TL;DR: The incorporation of time-of-flight information into the PET reconstruction process promises to further enhance the capabilities of fast PET devices by the improvement of temporal resolution through signal-to-noise ratio increase.

TL;DR: It appears reasonable that CCK or Sincalide cholecystography or cholescintigraphy may be detecting functional abnormalities before anatomic changes occur and can, therefore, serve as a useful examination in selecting symptomatic patients who may benefit from choleCystectomy.

TL;DR: Gastroesophageal scintigraphy is more sensitive than fluoroscopy, correlates well with clinical symptomatology, and is a reliable and convenient technique for the quantitative estimation of reflux before and after therapy.

TL;DR: The diagnostic work-up of the urologic patient must be tailored to the presenting symptom complex, carefully selecting from the many modilities available, those most likely to establish the diagnosis and extent of the suspected lesions.

TL;DR: Progress in the labeling of clinically useful tracers with suitable radionuclides is needed in order to achieve further significant progress in the areas of clinical applications.

TL;DR: In the past, T3 suppression testing was often required to confirm the presence of autonomous thyroid function in patients with borderline clinical and laboratory findings suggestive of hyperthyroidism or in euthyroid patients with the stigmata of Graves' disease, but the current availability of radioimmunoassays for triiodothyronine (T3) and thyrotorpin (TSH) plus the ability to evalate pituitary responsiveness by performing a TRH stimulation test permits a definitive

TL;DR: A 40-yr-old white male had a liver scan performed as a general workup for right upper quadrant pain and the liver was found to be devoid of any disease, thereby concluding that the defects seen in scintiscan were all pseudodefects.

TL;DR: 99m Tc-pertechnetrate breast scanning is employed in selected cases as a complement to mammography when the diagnosis was uncertain, and in such cases the combined use increased the diagnostic accuracy.

TL;DR: The management of patients with gastrointestinal (GI) bleeding depends on accurate localization of the site of hemorrhage and the introduction of the 99mTc-sulfur colloid technique has greatly simplified the evaluation and management.

TL;DR: The challenge to cardiovascular nuclear medicine is the prospective identification of patients who would benefit most from aggressive intervention aimed at preventing or reversing ischemic ventricular dysfunction.

TL;DR: Although radionuclide angiography has the capacity for advancing the understanding of the ventricular response to exercise, the technical limitations of this technique in specific diagnostic conditions has yet to be defined adequately.

TL;DR: The scan findings of missed torsion were confirmed at surgery when an infarcted right testicle was removed and an orchiopexy performed on the left.

TL;DR: The radionuclide superior venocavogram is a useful noninvasive tool for the evaluation of obstruction of this venous system and its response to treatment.

TL;DR: A 70-yr-old female referred for thyroid scanning because of a mass in her neck of increasing size over a 2-yr period was found to have an asymmetric thyroid gland, with the right lobe of thyroid displaced medially by a large cold nodule.
