The authors report a case of Fielding type II acute atlanto-axial rotatory fixation (AARF). The CT scan with coronal reconstruction showed an avulsion of the apical and right alar ligament. These findings are exceptionally reported in the literature, especially concerning the apical ligament which might be a stabiliser in flexion and extension of the occipitocervical joint.

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...

trauma is the most common reason in 1-34 years olds. in patient with multiple traumas, the head is the most common involved part. the importance of computed tomography (ct scan) in diagnosis of brain trauma is well established and ct of the brain is a choice method. finding lesion in brain traumatic patient is very important so goal of this study is finding of brain ct scan in traumatic patient...

introduction bolus is a soft and resilient material which is used for increasing skin dose or to even out the irregular patient contour. the main property of various materials used presently as bolus is the water-equivalent electron density. ethyl methacrylate is used as a soft-liner in dentistry and its physical and chemical properties are proved to be nontoxic for human body. the goal of this...

BACKGROUND AND PURPOSE Pediatric cranial sutures are often evaluated for abnormal diastasis upon presentation to the emergency department after trauma or during a neurologic consultation; however, few normative data for CT measurements exist. This study establishes normal means for the sagittal and coronal suture widths during the first year of life by using CT. MATERIALS AND METHODS The sagi...

Between 1980 and 1985, 35 patients (26 women and nine men) who had coronal CT scans of the sella turcica for suspected ACTH-secreting pituitary adenoma underwent transsphenoidal exploration. The CT examinations were performed with a fourth-generation EMI scanner (CT 7070). The reports of the preoperative CT examinations were compared with the findings at transsphenoidal exploration; in cases wi...

chronic rhinosinusitis (crs) is a common disease which is usually diagnosed clinically, considering the combination of natural history, physical examination and imaging studies. this study aimed to evaluate the clinical value of routine postoperative histopathologic examination (pohe) in patients with a clinical diagnosis of chronic rhinosinusitis with polyposis (crswp), or without polyposis (c...

in this study, 22 patients (15-75 years old) were selected and transferred to ct scan for tumor ablation. for ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. then, laser probe inserted through the needle and laser energy delivered. although we ...

A 25-year-old female presented with sudden-onset dyspnoea. A chest X-ray showed total atelectasis on the left haemithorax (Fig. 1). A chest computed tomography (CT) revealed a cystic mass in the posterior mediastinum that compressed the left main bronchus (Fig. 2). Pathological examination confirmed a broncho-genic cyst in the posterior mediastinum. Figure 1: Chest X-ray showing total atelectas...

BACKGROUND AND PURPOSE Early hematoma growth is one of the main determinants of mortality in patients with intracranial hemorrhage (ICH). Transcranial duplex sonography (TDS) might represent a useful tool for the bedside monitoring of early ICH enlargement. We aimed to correlate ICH volumes measured by TDS and CT scan in patients with ICH evaluated <3 hours of symptom onset. METHODS We prospe...
