results loss of consciousness (gcs drop or amnesia) was markedly associated with abnormal brain ct scan (p < 0.05). interestingly, we found 7 patients with normal clinical examination but significant abnormal brain ct scan. conclusions according to the results of our study, we recommend that all patients with minor head trauma underwent brain ct scan in order not to miss any life-threatening he...

magnetic resonance imaging (mri) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. the advantages and disadvantages of mri is not fully understood. in the computerized tumor (ct) scan, as an invasive method, the x-rays of the body is used for tomography; which different x-ray attenuation coefficient in tissues as well as...

OBJECTIVE At present, metastatic bone involvement is usually assessed using bone scintigraphy, which has a high sensitivity but a poor specificity. The objective of our study was to compare the sensibility of the 2-deoxy-2-[18F] fluoro-d-glucose positron emission tomography/computed tomography (F-18 FDG PET/CT) for the detection of bone metastasis in patients with non-small-cell lung cancer (NS...

Background: Jaw bone quality plays an essential role in treatment planning and prognosis of dental implants. Regarding several available methods for bone density measurements, they are not routinely used before implant surgery due to hard accessibility.Objective: An in vitro investigation of correlation between average gray scale in direct digital radiographs and Hounsfield units in CT-Scan pro...

 Preparing to manage weapons of mass destruction events challenges emergency services systems neighboring Syria every day. Understanding injury from explosives is essential for all providers of emergency care in both civilian and military settings. In this case, the authors present a 22-year-old man who was admitted to the emergency department with displaced skull fracture, epidural hemorrhage ...

Retrograde cystography and computed tomography (CT) are considered the gold standard for investigating bladder and pelvic bone injury. However, these methods can miss extraperitoneal bladder rupture caused by a penetrating bone fragment from a pelvic bone fracture. We experienced a routine conventional cystography and CT scan that failed to identify penetration of the bladder by a bone fragment...
