INTRODUCTION: Lumbar spondylolysis is defined as a defect or fracture of the pars interarticularis and can occur with or without anterior spondylolisthesis. This lesion is suspected to arise from repetitive trauma to the posterior elements of the spine and is a major cause of back pain in children; spondylolysis is found in approximately 6% of the pediatric/adolescent population as a whole and ...

Long-object problem and short-object problem both deal with reconstruction problems with truncated conebeam CT projections acquired with a helical path. They have significantly less practical limitations than original exact cone-beam CT reconstruction algorithms which the cone-beam must cover the whole object. The short-object problem can be defined as reconstruction of the whole object having ...

A 15-year-old adolescent presented to us with mild headache, progressive dizziness and recent vomiting since 2 weeks without seizures. There was a history of head injury (neglected) following a stone-throwing incident 2 months earlier. On examination, he was conscious with a left cerebellar syndrome but without other neurologic deficit. Routine biologic data were normal. CT-scan revealed left p...

BACKGROUND AND PURPOSE Clinicians are insecure reading CT scans by using the one-third rule for acute middle cerebral artery stroke (1/3 MCA rule) before treating patients with recombinant tissue plasminogen activator. The 1/3 MCA rule is a poorly defined volumetric estimate of the size of cerebral infarction of the MCA. A 10-point quantitative topographic CT scan score, the Alberta Stroke Prog...

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...

The pineal gland is very important human endocrine gland and its location and size is very important for the neurologist and neurosurgeons and for the radiologist because in certain radiological investigations it is the guide of midline and its right or left shifting is highly suggestive of space occupying lesion in the brain. The aim of study was to find out the morphometric parameters of pine...

Background: CT scans with contrast media administration have been used to confirm the presence of pathology in blood vessel brain. High accuracy and fast scanning time produced by make this modality main choice assessing aneurysm Technological advances development CT-helical image acquisition techniques enabled neuroradiologists evaluate brain aneurysms a short time. Magnetic resonance (MR) ang...

Background: Trans-pedicular screw placements have been an increasingly popular procedure in many neurosurgery and orthopedic departments. Any mistake at performing the technique could be followed by irreversible neurological deficit and damage of Para spinal vital structures as well as less stability for future fusion. Objectives: In this study we tried to show the benefits and capabilities of ...

Background: Evaluation of a patient with chronic rhinosinusitis also requires proper radiological examination apart from otolaryngological examination and diagnostic nasal endoscopy. Various anatomical variations can be seen on CT Scan of nose and paranasal sinuses. Methods: This was a prospective cross sectional study carried out in department of ENT at Government Medical College &Dr. Susheela...
