MDCT angiography of the spinal vasculature and the artery of Adamkiewicz.
The purpose of our study was to prospectively assess 40-MDCT technology in combination with adapted brain reconstruction algorithms to visualize the spinal vasculature, in particular the artery of Adamkiewicz and its anatomic variants. ⋯ Contrast-enhanced 40-MDCT technology, in combination with an adapted brain reconstruction algorithm, can depict the artery of Adamkiewicz and its anatomic variants.

The purpose of this study is to show how sonography can reveal pathology of the eye and to highlight its usefulness as a simple and cost-effective tool in investigating eye symptoms. ⋯ The cystic nature of the eye, its superficial location, and high-frequency transducers make it possible to clearly show normal anatomy and pathology such as tumors, retinal detachment, vitreous hemorrhage, foreign bodies, and vascular malformations. Sonography is useful as a treatment follow-up technique because it has no adverse effects. Sonography is well tolerated by patients and relatively easy to perform for those familiar with real-time sonography.

Correlation of relative permeability and relative cerebral blood volume in high-grade cerebral neoplasms.
The purpose of this study was to correlate the degree of contrast enhancement on dynamic contrast-enhanced T1-weighted MRI and the relative cerebral blood volume (rCBV) values on T2*-weighted MRI in patients with high-grade brain neoplasms. ⋯ We found a high correlation between degree of contrast enhancement on dynamic contrast-enhanced images and rCBV values in whole tumors and in regions having the highest degree of contrast enhancement in this small study. Our findings, which suggest that relative permeability and rCBV values may be correlated in high-grade glial neoplasms, deserve further study in a larger patient population.

Localization of appendix with MDCT and influence of findings on choice of appendectomy incision.
The purpose of this study was to show the relation between McBurney's point and the appendix in patients undergoing 3D MDCT and to investigate the effect of this information on a surgeon's choice of appendectomy incision. ⋯ The location of the appendix varies widely among individuals, and McBurney's point has limitations as an anatomic landmark. Three-dimensional MDCT findings can be useful to surgeons customizing appendectomy incisions. Additional information about the location of the appendix in the CT report (if possible, together with a 3D image showing the location of the appendix) may be beneficial for surgeons performing appendectomy.

Epidemiologic, clinical, and imaging findings in brucellosis patients with osteoarticular involvement.
The aim of this study was to assess the epidemiologic and clinical features, complications, imaging findings, and outcomes for brucellosis patients with osteoarticular involvement. ⋯ Brucellosis is endemic to some regions. MRI is the method of choice for diagnosing osteoarticular and spinal complications of human brucellosis, especially during the early phase. It is important to differentiate tuberculous spondylodiskitis from brucellar spondylodiskitis because proper treatment for each of these diseases can prevent complications. The radiologic findings for these two forms of spondylodiskitis are similar, so serologic testing for brucellosis is necessary in such cases.
