The mastoid air cell system (MACS) protects the structures in ear and regulates pressure cavity. MACS segmentation is very difficult because of many overlapping object characteristics temporal bone. This study aims to accurately identify measure areas from CT-scan images mastoiditis patients. data tested consisted 128 CT 13 different Images were taken using Siemens SOMATOM Perspective Scanner m...

Clinical presentation asymptomatic, rarely presented facial asymmetry, swelling, pain, bowing long bones. Radiological investigations are computed tomograph...

b-cell lymphoblastic lymphoma (b-lbl) is an uncommon subtype of pediatric non-hodgkin lymphoma (nhl) which rarely involves the skin primarily. the positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-d: -glucose integrated with computed tomography (18f-fdg pet/ct) scan findings of a 8-year-old boy with cutaneous b-lbl were presented. pet/ct scan demonstrated mild fdg uptake in the ...

introduction: squamous cell carcinoma (scc) is the most common head and neck malignancy. to decrease the side effects of treatment and mortality from disease relapse, careful staging for the proper treatment plan is necessary. the main purpose of this prospective study is to compare the diagnostic value of computed tomography (ct) and magnetic resonance im-aging (mri) in oral scc and its lymph ...

Thirty-four such cases were identified from a 7-year period and their case notes were reviewed. The mechanisms of injury included:falls outdoors (15 cases), falls in the home (eight cases), road traffic accidents (RTAs; seven cases), missiles (...

Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods:...
