<b><i>Background:</i></b> Pulmonary embolism (PE) is diagnosed either by ventilation/perfusion (V/Q) scintigraphy or pulmonary CT angiography. One of the imaging methods used in nuclear medicine hybrid SPECT/CT scintigraphy. <b><i>Objectives:</i></b> The aim this study was to evaluate utility SPECT/CT(Q) diagnosis PE and compare with planar(Q) SPECT(Q) methods. <b><i>Methods:</i></b> group consisted 109 consecutive...
The aim of the study was to estimate sensitivity ¹⁸F-FCH PET/CT in preoperative localisation hyperfunctioning parathyroid glands patients with primary hyperparathyroidism (PHPT).Sixty-five consecutive PHPT, who underwent neck ultrasound (US) and 99mTc/99mTc-MIBI dual-phase scintigraphy, were prospectively enrolled. Twenty-two had unsuccessful surgery prior study. scans performed 65.0 ± 13.3 min after injection 218.5 31.9 MBq 18F-fluorocholine (FCH). Three experienced nuclear medicine...
Non-iodine avid metastases of differentiated thyroid cancer (DTC) can be found using PET/CT with a fluorine-18-labeled glucose analog ([
The mT/N1 ratio, PAD, and AAD can be used as predictors of tumor response to SIRT treatment, SPECT/CT imaging for dosimetric assessment radioembolization.
This paper presents a case of an 80-year-old man with idiopathic thrombocytopenic purpura after splenectomy performed many years ago, which normalized platelet count, presented severe thrombocytopenia no response to treatment. A SPECT/CT study was using 99mTc-labelled Sn-colloid. The histology confirmed the presence splenic tissue in those foci. Spleen examination (SPECT/CT) Sn-colloid is able detect and our opinion simpler less time-consuming procedure than 99mTc DRBC.
Sentinel lymph node (SLN) mapping is currently a routine technique in breast cancer management and preoperative scintigraphic imaging plays crucial role the process of SLN detection. The guidelines recommend performing planar acquisition optional single-photon emission tomography/computed tomography (SPECT/CT) imaging. aim this study was to verify whether SPECT/CT addition increases sensitivity detection patients with early-stage cancer. secondary aims were compare radionuclide...
A novel cardiac SPECT camera with cadmium-zinc-telluride (CZT) based technology has a fixed array of semiconductor detectors paired pinhole collimators focused on the heart. Image acquisition in obese patients can be challenging because much smaller detector field view compared to conventional gamma cameras. The aim this study was evaluate impact high body mass feasibility CZT myocardial perfusion imaging (MPI). additional investigate mechanism banana-shaped/obesity artifact, as referred...
About 30% of patients with disseminated differentiated thyroid cancer (DTC) may experience a loss iodine uptake. It is associated higher aggressiveness the tumour and reduced 10-year survival rate. The diagnosis non-radioiodine avid DTC metastases remains diagnostic challenge. A helpful technique for this positron emission tomography 2-[¹⁸F]fluoro-2-deoxy-D-glucose (PET/CT [¹⁸F]FDG). On other hand, there are still discussions about clinical value using exogenous thyroid-stimulating hormone...
An asymptomatic Caucasian male patient underwent coronaryartery disease diagnostics. Standard exercise treadmilltest was inconclusive, and Holter ECG study didn’t show anysignificant abnormalities. Considering the high risk of ischemicheart diseasenuclear stress test performed,which revealed ST-segment elevation in recovery phase ofthe treadmill test. Single photon emission computedtomography (SPECT/CT) showed myocardial perfusion abnormalitiesin inferior lateral walls left ventricle....

Abstract We propose a new in vitro model to assess the impact of 90 Y-microspheres derived low-dose beta radiation on colorectal cancer cell line under various oxygenation conditions that mimic tumor environment. Cancer cells (HCT116) proliferation was assessed using Alamar Blue (AB) assay after 48, 72, and 96 h. FLUKA code changes populations relative absorbed dose. In normoxia, mitochondrial activity measured by 48–72 h significantly correlated with number microspheres (48 h: r = 0.87 72...
Abstract Aim: to estimate sensitivity of 18F-FCH PET/CT in preoperative localisation hyperfunctioning parathyroid glands patients with primary hyperparathyroidism (PHPT). Methods: 65 consecutive PHPT who underwent neck ultrasound (US) and 99mTc/99mTc-MIBI dual-phase scintigraphy were prospectively enrolled. Twenty-two had unsuccessful surgery prior the study. scans performed 65.0 ± 13.3 min after injection 218.5 31.9 MBq 18F-fluorocholine (FCH). Three experienced nuclear medicine physicians...
Introduction: This study was designed to assess quantitatively a safe position of the microcatheter during SIRT (Selective Internal Radiation Therapy) procedure, in order minimize risk non-target spheres leaking. Materials and Methods: Retrospective analysis distance tip from coiled or patent arteries measured 99mTc-MAA work-up procedure. Frequency extrahepatic leaking procedures evaluated. Results: There were 85 patients who underwent 98 procedures. 64 radioembolizations. 44 gastroduodenal,...
Abstract Purpose: We aimed to find the minimum feasible dose of fluorodeoxyglucose (18F-FDG) in positron emission tomography/computed tomography (PET/CT) Hodgkin lymphoma patients performed on a camera with bismuth germanate (BGO) crystals. Methods: Ninety-one 18F-FDG PET/CT scans decreasing time per bed position (2 min, 1.5 1 50 sec, 40 30 sec and 20 sec) were assessed evaluate image quality. Mean administered was 3.0±0.1 MBq/kg mean uptake 54.0±8.7 min. The series quality subjectively...
BACKGROUND: Myocardial perfusion scintigraphy remains one of the substantial noninvasive diagnostic methods in coronary artery disease. Recent technological advancement allowed to create novel semiconductor, dedicated cardiac gamma camera with better spatial resolution and higher energy resolution, resulting reduction radiation burden acquisition time.

BACKGROUND:Tuberous sclerosis complex (TSC; Bourneville-Pringle disease) is a multisystem genetic disorder manifesting as benign tumors that can affect any system. Malignant neoplasm may coexist in patients with TSC. In such cases, there are diagnostic difficulties distinguishing between metastatic lesions and changes. We show the usefulness of positron emission tomography (PET) resolving these difficulties. CASE REPORT:The purpose this article to present metabolic imaging using...
