Perfusable tissue index (PTI) is a marker of myocardial viability and requires acquisition of transmission, [O]CO and [O]H2O scans. The aim of this study was to generate parametric PTI images from a [O]H2O PET/CT scan without an additional [O]CO scan. Methods: Data from 20 patients undergoing both [O]H2O and [ O]CO scans were used, assessing correlation between PTI based on [O]CO (PTICO) and on...

A method for automatic extraction and labeling of the airway tree from thoracic CT scans is presented and extensively evaluated on 150 scans of clinical dose, low dose and ultra-low dose data, in inspiration and expiration from both relatively healthy and severely ill patients. The method uses adaptive thresholds while growing the airways and it is shown that this strategy leads to a substantia...

background focused assessment with sonography for trauma (fast) is a precise, non-invasive, and low cost method to assess free abdominal fluid in trauma patients. objective this study assessed the relationship between free intra-abdominal fluid and organ injury in blunt abdominal trauma and designed a scoring system based on fast. patients and methods a total of 200 patients with blunt abdomina...

trauma is the leading cause of death in united states in the younger population. cardiac trauma is common following blunt chest injuries and is associated with high morbidity and mortality. this study discusses various multidetector computed tomography (mdct) findings of cardiac trauma. cardiac injuries are broadly categorized into the most commonly occurring blunt cardiac injury and the less c...

various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution ct scan. it was found that in approximately one third of the patient group (with idiopathic snhl), the vestibular aqueduct was 1.5 mm or larger. also...

background and aims: one of the most common injuries around the world is the traumatic injury of the spine and spinal cord with unknown worldwide situation of traumatic spinal cord injury (tsci) affecting on the effectiveness of preventive policy programs. in addition, because of possibility of making paralysis, the potential injury to the spine could be one of the most important traumas and a ...

  Background: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures.   Methods: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, ye...

Abstract The principles of nasal reconstruction include the need to reconstruct three tissue layers, restore entire skin aesthetical units, and, possibly, replacement with like tissues. Computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies were applied two total reconstructions in male patients who underwent rhinectomy for cancer. Three-dimensional (3D) data obtained f...
