introduction:visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. optical coherence tomography (oct) is a high-resolution imaging technology which may be used for the visualization of tissues. in this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.materials and methods:thr...

background and aims. the imaging techniques commonly used for foreign body detection include plain radiography, xeroradiography, computed tomography (ct) scans, magnetic resonance imaging (mri) and ultrasonography. the aim of the present study was to compare cone-beam computed tomography (cbct) with conventional ct scan in determination of the exact location of a foreign body in the maxillofaci...

Study design: Case reports of abnormal appearance of hemangioma in thoracolumbar spine in bone scintigraphy. Objective: To report an unusual presentation of spinal hemangioma mimicking metastasis in bone scintigraphy and SPECT-CT. Summary of back ground data: Spinal hemangiomas are usually incidental findings. Most of them are asymptomatic and bone scintigraphy will be normal in majority of the...

chronic recurrent multifocal osteomyelitis (crmo) is an inflammatory bone disease usually affecting children. a 9-year old boy presented with recurrent lower extremities pain and discomfort lasting for two years. in every time, symptoms vanished after several weeks. the patient received antibiotics only in one period of bone pain. in other occasions the patient didn’t received any antibiotics. ...

PURPOSE Bone scintigraphy is the standard of reference in bone metastases in prostate cancer patients. However, new radiotracers employed in prostate-specific membrane antigen (PSMA)-ligands has led to the growing importance of PET/CT as diagnostic tool. The aim of our study was to investigate the difference between bone scan and PSMA-PET/CT for the detection of bone metastases in prostate canc...

Computed tomographic (CT) findings in 18 patients with temporal bone trauma were reviewed. Eight patients suffered longitudinal fractures of the petrous bone, which were associated with ossicular dislocation in two patients. Transverse fractures were detected in six patients, with a contralateral mastoid fracture in one patient. In four patients, the fractures were restricted to the mastoid reg...

Introduction: Congenital vomer agenesis is an extremely rare condition in which the vomer bone does not fully develop, which can lead to septal perforation. Case Report: We report two cases with a defect in the vomer bone in the posteroinferior portion of the septum, found accidentally while performing a pre-operative CT scan for nasal obstruction evaluation. They were diagnosed with congenital...

A male patient aged 71 with a history of urothelial bladder cancer which was treated one year previously with a transurethral resection (stage pT1G3) and BCG intravesical instillations. He presented at the surgery with a week-long history of right eye closure failure and twitching of the corner of his mouth towards the left. He also stated a 3-month occurrence of earache and temporal right pain...

MR images of the intratemporal portion of the facial nerve were obtained with surface coils using a 0.3-T permanent magnet whole-body imaging system. Various 2DFT spin-echo pulse sequences were used to produce 5-mm thick sections with 0.5-mm pixels on a 512 X 512 acquisition matrix. The MR images from normal volunteers were correlated with cryosection specimens of three fresh human cadavers. Th...
