Introduction: The purpose of this study was to develop a statistical model for prediction of radiation induced sensorineural hearing loss (SNHL) induced by radiotherapy in patients with brain tumors.   Materials and Methods: CT scan of 18 patients (10 males and 8 females) with brain tumor who were referred to Radiation Center of Milad Hospital in Isfahan in 2...

Optic nerve sheath diameter measurement (ONSD) has been associated with identifying the prognosis of traumatic brain injury (TBI) patients. The study was planned to evaluate the prognostic value of ONSD measured on the initial brain computed tomography (CT) scan performed on patients with blunt TBI in the emergency department(ED). This retrospective cross-sectional study was conducted at the Ag...

Introduction: Epilepsy is a neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain. Epileptic seizures are episodes that can vary from brief and nearly undetectable to long periods of vigorous shaking. These episodes can result in physical injuries to the patients. Aim: To...

An alternative pseudo CT generation method for magnetic resonance image (MRI)-based radiotherapy planning was investigated in the work. A pseudo CT was initially generated using the rigid image registration between the planning MRI and previously acquired diagnostic CT scan. The pseudo CT generated was then refined to have the same morphology with that of the referenced planning image scan by a...

BACKGROUND AND OBJECTIVE Pediatric traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Computed tomography (CT) is the modality of choice to screen for brain injuries. MRI may provide more clinically relevant information. The purpose of this study was to compare lesion detection between CT and MRI after TBI. METHODS Retrospective cohort of children (0-21 ye...

abstract: gestational trophoblastic neoplasm (gtn) is among rare human tumors which can be observed with widespread metastasis. two young patients with emergent neurologic symptoms with no gynecological problems are presented in this report. gtn was later diagnosed in both cases with brain metastasis. the first case: a 22 years old patient, admitted to the infectious disease ward, with probable...

Some intraventricular mass lesions have proven difficult to delineate, even with a contrast-enhanced CT scan. The combination of intrathecal contrast and CT scanning has been especially useful in studying the ventricles and subarachnoid spaces of both the brain and spinal cord . We report a case in which we instilled metrizamide directly into the body of the left lateral ventricle to show the e...

a 49 year old woman diagnosed as a cervical cancer patient, after receiving appropriate treatment experienced metastasis in her abdominopelvic cavity. after aggressive management, she was well for a while. however, she developed to a poor condition consisting of urologic, gastroenterological, hematologic and neurologic problems just in a short time. in the course of hospital she presented one s...

Background and purpose: Proper diagnosis of patients with COVID-19 is one of the challenges in medical centers. RT-PCR is the standard and reference test in diagnosis of patients with COVID-19. This study aimed at accelerating the correct diagnosis of COVID-19 and the diagnostic power of chest CT scan and RT-PCR. Materials and methods: This study was performed in 569 patients with COVID-19 adm...
