introduction: the main purpose of this study was to compare transient ischemic dilation (tid) ratios in spect-low dose ct and spect myocardial perfusion imaging (mpi) by application of different quantitative programs and quantify the possible shift in the upper normal limits of tid ratio in the spect-ct mpi. methods: 149 patients with low pre-test probability for coronary artery disease (cad),...

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 ...

Aim: Assess the role of hybrid modality SPECT/CT versus planar scintigraphy in sentinel lymph node (SLN) identification patients with breast cancer. Methods: Planar and were performed 23 women cancer (mean age 59.5 years range 25 - 82 years) invasive (T0, T1 T2), without clinical evidence axillary metastases (N0) no remote (M0), radiocolloid was injected four subareolar sites. images separately...

Introduction: Patients with essential tremor (ET) have 3.5 times greater risk of developing Parkinson's disease (PD) throughout their lives, also known as PD antecedent ET (ET-PD). Single photon emission computed tomography radiotracer imaging dopamine transporters (TRODAT-SPECT) can help differentiate these two diseases. Method: Relate the results TRODAT-SPECT in patients to potential progress...

Background: Hairline rib fracture commonly happens after blunt trauma, and it is hard to be detected by X-ray. Many methods can used, among them, the hybrid image of single-photon emission computed tomography (SPECT) (CT) seems produce higher sensitivity for diagnosis. Case presentation: A 63-year-old man came our rehabilitation clinic a vehicle accident 25 days earlier. He had multiple plain f...

Cilj: Cilj rada bio je procijeniti doprinos jednofotonske emisijske tomografije / kompjutorizirane somatostatinskih receptora (SR SPECT/CT) s 99mTc-EDDA/HYNIC-Tyr3-oktreotidom (99mTc-Tektrotyd) u dijagnostici i procjeni proširenosti bolesti kod pacijenata oboljelih od neuroendokrinih tumora (NET-ova). Ispitanici metode: Retrospektivno analizirano 120 SR SPECT/CT snimanja patohistološki dokazani...

Post stroke dementia is one of the most common complications of stroke that is preventable and relatively treatable too. The purpose of the study is comparison between the positive findings in brain CT scan and brain perfusion SPECT. 15 patients who were complicated by dementia after cerebrovascular accident and also 5 patients as a control group enrolled in this study. Brain CT scan and ...

PURPOSE We developed a method of image data projection of bone SPECT into 3D volume-rendered CT images for 3D SPECT/CT fusion. The aims of our study were to evaluate its feasibility and clinical usefulness. METHODS Whole-body bone scintigraphy (WB) and SPECT/CT scans were performed in 318 cancer patients using a dedicated SPECT/CT systems. Volume data of bone SPECT and CT were fused to obtain...

OBJECTIVE Comparison of 201Tl chloride SPECT (TI-SPECT) with 99mTc-MIBI SPECT (MIBI-SPECT) in the depiction of malignant head and neck tumors was prospectively studied. METHODS Forty-one patients with various tumors of the head and neck were included in this prospective study. Histologically, 36 patients had squamous cell carcinomas, 3 undifferentiated carcinomas, 1 transitional cell carcinom...
