Allergy is an important consideration in the evaluation of patients with rhinosinusitis. Several studies have addressed staging systems for rhinosinusitis based on extent disease present computed tomography (CT) scanning. The severity and sinus CT imaging helps guide decisions regarding medical surgical treatment options. This study evaluates allergic nonallergic patients. A total 42 at our institution underwent both modified RAST coronal scan their symptoms. single, blinded staff...

MR imaging has been used extensively for identification and determination of chronicity VCF. A major emphasis is placed on edema or fluid clefts within the vertebral body. Little attention given to other spinal structures such as endplate, intervertebral disk, posterior elements, facet joints, ligaments, paraspinal musculature. Our objective was assess incidence endplate adjacent-level disk injury seen studies patients with acute subacute painful osteoporotic compression fractures.We...
