Automatic Cobb Angle Measurement System by Using Nuclear Medicine Whole Body Bone Scan
نویسندگان
چکیده
Evaluation of scoliosis is performed traditionally by means of standing posterior-anterior radiographs of the full spine to assess lateral curvature with the Cobb method. In this paper, we present a new automatic algorithm to measure Cobb angle by using nuclear medicine whole body bone scan images. Our algorithm design is based on the fuzzy sets histogram thresholding, anatomical knowledge-based image segmentation method, and morphology technology. It is expected that the results may help physicians to diagnose scoliosis via the scintigraphy images, and thus to reduce radiation done to patients.

A Semi-Automatic Algorithm for Estimating Cobb Angle
Background: Scoliosis is the most common type of spinal deformity. A universal and standard method for evaluating scoliosis is Cobb angle measurement, but several studies have shown that there is intra- and inter- observer variation in measuring cobb angle manually.Objective: Develop a computer- assisted system to decrease operator-dependent errors in Cobb angle measurement.Methods: The spinal ...
متن کاملComparison of 99mTc-MDP and 99mTc-MIBI whole body scans for diagnosis of widespread skeletal metastases [Persian]
Skeletal metastasis is one of the most important disabling complications of the malignant diseases. As in general, the survival of patients with osteometastatic lesions is relatively long, an early diagnosis can lead to improve the patient’s life, both quantitatively and qualitatively, and prevent exacerbation of the disease and disabling complications. In this study, 22 patients with est...

A 73-year-old man with history of prostatic adenocarcinoma radical prostatectomy underwent 99mTc-MDP whole-body bone scan and subsequent 68Ga-labeled prostate-specific membrane antigen (PSMA) ligand PET/CT for restaging due to a gradual rise of prostate-specific antigen levels. Whole-body bone scan showed two focal zones of slightly increased uptake in the right fronto-par...

This report presents a 3.5-year-old boy who was hospitalized for limping. Medical history and physical exams were not suggestive for any definitive diagnosis. Laboratory and radiographic exams did not support any specific diagnosis either. Subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.
