Abstract Background SPECT/CT has been applied for preoperative planning of MRONJ. Furthermore, the SUV using bone enabled quantitative analysis jaw lesions. This study aimed to evaluate role SUVs in MRONJ, especially relation CBCT and histopathological findings resected mandibulectomy. The preliminary was conducted on five MRONJ patients who underwent mandibulectomy after SPECT/CT. Results SUVm...

Cranial osteomyelitis is a potentially fatal lesion. White blood cell scanning (WBC) with 99mTc-hexamethylpropylene amine oxime (HMPAO) has proven highly sensitive and specific in the diagnosis and follow-up of patients with suspected osteomyelitis. In this report we show the usefulness of SPECT and transmission CT performed simultaneously using a hybrid imaging device for the functional anatom...

INTRODUCTION A physical 3-dimensional phantom that simulates PET/SPECT images of static regional cerebral blood flow in grey matter with a realistic head contour has been developed. This study examined the feasibility of using this phantom for evaluating PET/SPECT images. METHODS The phantom was constructed using a transparent, hydrophobic photo-curable polymer with a laser-modelling techniqu...

BACKGROUND xSPECT Bone® (xB) is a new reconstruction algorithm developed by Siemens® in bone hybrid imaging (SPECT/CT). A CT-based tissue segmentation is incorporated into SPECT reconstruction to provide SPECT images with bone anatomy appearance. The objectives of this study were to assess xB/CT reconstruction diagnostic reliability and accuracy in comparison with Flash 3D® (F3D)/CT in clinical...

PURPOSE The purpose of this study was to compare the diagnostic performance of SPECT/CT and MRI in patients with ankle and foot pain, with regard to the lesion types. MATERIALS AND METHODS Fifty consecutive patients with ankle and foot pain, who underwent 99mTc-MDP SPECT/CT and MRI, were retrospectively enrolled in this study. Symptomatic lesions were determined based on clinical examination ...

Abstract Prostate cancer is one of the most common cancers affecting men. Bone scan part staging modality commonly used to evaluate bone metastasis. A with diffused increased skeletal tracer uptake relative soft tissue, combined faint renal activity known as a superscan. However, primary concern are false negatives associated scans, where diffuse metastasis indistinguishable on superscans. In t...

PURPOSE The role of fusion imaging methods SPECT-CT and PET-CT is currently being investigated in radiotherapy (RT) treatment planning. SPECT and PET provide extra information for gross tumor volume (GTV) delineation. The purpose of this study was to evaluate the role of SPECT-CT in RT. METHODS SPECT-CT studies were performed in 55 patients with (99m)Tc-MIBI/Tetrofosmin (TF), with 99mTc-Nanoc...

UNLABELLED The purpose of this study was to compare a routine bone SPECT/CT protocol using CT reconstructed with filtered backprojection (FBP) with an optimized protocol using low-dose CT images reconstructed with adaptive statistical iterative reconstruction (ASiR). METHODS In this prospective study, enrolled patients underwent bone SPECT/CT, with 1 SPECT acquisition followed by 2 randomized...

Inguinoscrotal hernias that contain bladder diverticulae are a rare occurrence. We report the case of a 85 yearold man with intense radioactivity overlying the left pubic tubercle on [Tc99m]-methylene-diphosponate (MDP) bone scan. SPECT/CT imaging established the diagnosis of excreted urinary radioactivity within a large herniated bladder diverticulum. SPECT/CT is a useful technique for evaluat...
