UNLABELLED Planar lung scintigraphy is a standard method used for the diagnosis of lung embolism, but it is hampered by the high incidence of nondiagnostic tests. Ventilation/perfusion SPECT may possibly improve this situation. The objective of this study was to compare planar lung scintigraphy with ventilation/perfusion SPECT using pigs with artificially engendered lung emboli labeled with (20...

OBJECTIVE The diagnosis of active inflammation in ankylosing spondylitis (AS) is crucial for treatment to delay possible persistent deformities. There are no specific laboratory tests and imaging methods to clarify the active disease. We evaluated the value of Tc-99m human immunoglobulin (HIG) scintigraphy in detection of active inflammation. MATERIAL AND METHODS Twenty-nine patients were inc...

AIM The bone scintigraphy is indicated in patients with costochondral pain in order to identify the organic etiology. We aimed to investigate the local and projecting pain, or incidental findings in the three phase bone scintigraphy of the patients referred for costochondral pain. METHODS We included 50 patients (36F, 24M; mean: 41±18 years-old) referred to our department for three phase bone...

INTRODUCTION Scintigraphy with technetium-sestamibi (MIBI) is the test of choice for localising adenomas in patients with primary hyperparathyroidism (PHPT). In some studies it has emerged that the increase in sensitivity of this test could be associated with a decrease in the uptake of the radiotracer by the thyroid gland. The aim of this study is to analyse our experience in patients with a n...

PURPOSE This study examined whether multidetector computed tomography (CT) is superior to bone scintigraphy for diagnosis of an occult scaphoid fracture. METHODS AND MATERIALS In a study period of 22 months, 100 consecutive patients with a clinically suspected scaphoid fracture and no fracture on scaphoid radiographs, were evaluated with CT within 24 hours after injury and bone scintigraphy b...

 Background: Bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. But surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance....

We present a 55-year old male patient who was subjected to whole body skeletal scintigraphy for metastatic work up of urinary bladder cancer. Whole body 99mTc-methylene diphosphonate (MDP) skeletal scintigraphy was performed. That revealed no skeletal metastasis in the entire body skeleton and normally visualized left kidney with empty right renal fossa. Additionally tracer activity ...

A 63-year-old woman presented with a history of hyperthyroidism symptoms over two years, referred for thyroid scintigraphy. In the hospital archives we have met her previous thyroid scintigraphy showing a hot nodule in the upper part of right thyroid lobe. However, her recent thyroid scintigraphy was showing only cold nodules but no hot nodule, giving an impression that she had some treatment t...
