PURPOSE The use of SPECT/CT in bone scans has been widespread in recent years, but there are no specific guidelines concerning the optimal acquisition protocol. Two strategies have been proposed: targeted SPECT/CT for equivocal lesions detected on planar images or systematic whole-body SPECT/CT. Our aim was to compare the diagnostic accuracy of the two approaches. METHODS 212 consecutive pati...

In view of the commercial success of integrated PET/CT scanners, there is an increasing interest in comparable SPECT/CT systems. SPECT in combination with CT enables a direct correlation of anatomic information and functional information, resulting in better localization and definition of scintigraphic findings. Besides anatomic referencing, the added value of CT coregistration is based on the ...

objective(s): in this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/computed tomography (spect/ct) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. methods: five patients with primary hyperparathyroidism (phpt) and 4 patients with secondary hyperparathyroidism (shpt) we...

UNLABELLED The purpose of this study was to determine the diagnostic value of 131I SPECT/spiral CT (SPECT/CT) on nodal staging of patients with thyroid carcinoma at the first ablative radioiodine therapy. METHODS Fifty-seven patients were studied using SPECT/CT 3-4 d after receiving 3.96+/-0.5 GBq of 131I for radioablation of thyroid remnants after a thyroidectomy for differentiated thyroid c...

UNLABELLED The present study evaluated the role of SPECT/CT as an adjunct to (67)Ga (GS) or (111)In-labeled white blood cell (WBC) scintigraphy for diagnosis or localization of infection. METHODS Eighty-two patients (56 male and 26 female; mean age, 62 y) assessed for known or suspected infectious processes underwent 88 SPECT/CT studies. Forty-seven patients underwent GS SPECT/CT (13 with fev...

Background: The standard treatment for locally advanced non-small cell lung cancer (LA-NSCLC) is represented by concomitant chemo-radiotherapy followed consolidation with durvalumab that ensures a 5-year survival of 46%. However, the risk radiotherapy-induced pneumonia (RIP) almost 10–15%. Complete cardiological examination also usually performed during cardiopulmonary pre-treatment evaluation ...

OBJECTIVE To assess the clinical utility of SPECT/ CT in subjects with endocrine and neuroendocrine tumors compared to SPECT alone. MATERIAL AND METHODS 48 subjects (31 women;17 men; mean age 54±11) with clinical suspicion or diagnosis of endocrine and neuroendocrine tumor had 50 SPECT/CT scans (32 Tc-99m MIBI, 5 post treatment I-131, 8 In-111 Pentetreotide, and 5 I-123 MIBG). SPECT alone fin...

Objectives This retrospective study evaluated whether the use of additional anterior 99mTc-sestamibi/123I pinhole imaging improves the outcome of 99mTc-sestamibi/123I subtraction SPECT/CT in parathyroid scintigraphy (PS). Materials and Methods PS using simultaneous dual-isotope subtraction methods and an acquisition protocol combining SPECT/CT and planar pinhole imaging was performed for 175 ...

The goal of this study was to present a method for physiologic validation and show results for a comparison of the 4D-CT ventilation and SPECT ventilation or perfusion. A 4D-CT and a SPECT ventilation/perfusion (V/Q) (VSPECT and QSPECT) scans were acquired for a lung cancer patient. Two 4D-CT ventilation images were created using two metrics: Hounsfield unit (HU)-change (V4D-CT) and Jacobian de...
