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...

errors and variations in interpretation can happen in clinical imaging. few studies have examined the biased effect of clinical information on reporting of brain ct scans. in a blinded double crossover design, we studied whether three radiologists were biased by clinical information when making ct scan diagnosis of the brain. three consultant radiologists in three rounds with at least a one-mon...

ct image quality has been affected by many factors such as kvp, ma, exposure time, alogorithm and section thickness. gantry tilt has the main role in visualization of the temporal bone anatomic structures. in this study, we tried to optimize these factors to determine the best gantry tilt. this study was performed on the human skull phantom and then extended to 15 patients. the phantom was made...

BACKGROUND CT scan has replaced most of the invasive techniques in diagnosis of brain tumours because it can accurately demonstrate, localize and characterize the brain tumours. The objective of this study was to observe the accuracy of CT scan in the diagnosis of brain tumours in children by comparing it with histopathology. This descriptive case series was conducted at Department of Radiology...

Background: Brain trauma (BT) is the most common cause of death among children worldwide. In traumatic patient, the skull is the most common involved part. The importance of computed tomography (CT) scan in diagnosis of BT is well established. CT scan is actually a common option for evaluation of patients with cranial trauma. Considering the importance of CT scan in the diagnosis of brain lesio...
