CT angiography of cervical anterior spinal artery and anterior radicular artery: preliminary study on technology and its clinical application.

Spinal cord ischemia significantly threatens patient health. Cervical spinal cord ischemia is mainly caused by anterior spinal artery (ASA) or anterior radicular artery (ARA) injury. Because of the complex hemodynamics in cervical spinal cord arteries, conventional CT angiography (CTA) does not satisfactorily show the ASA and ARA.

Cantrell syndrome with complex cardiac malformations: a case report.

Cantrell syndrome is a rare condition of congenital defects of 5 developmentally associated structures: the abdominal wall, sternum, diaphragm, pericardium, and heart. Few patients survive, and even fewer survive with good outcomes of quality of life. We present a case with the pentalogy and profound cardiac malformations.

MRI findings of primary CNS lymphoma in 26 immunocompetent patients.

Objective: To record the MR imaging features of primary central nervous system lymphoma (PCNSL) and compare these features in monofocal and multifocal disease.

Materials And Methods: Twenty-one cases of monofocal disease were compared to five cases of multifocal disease. All patients were examined by non-enhanced and contrast-enhanced MRI.

[Imaging diagnosis of the vertebral injury in earthquake].

Objective: To explore the clinical value of imaging diagnosis of the vertebral injury in earthquake.

Methods: Twenty-two cases of the vertebral injury in earthquake with clinical and imaging data were analyzed retrospectively. All of the cases were performed X-ray plain film examination, CT in 20 cases and MRI in 15 cases.

MR imaging of tumor angiogenesis using sterically stabilized Gd-DTPA liposomes targeted to CD105.

Aim: To depict tumor angiogenesis via the expression of CD105 in tumor-bearing rats using Gd-DTPA liposomes targeted to CD105 (CD105-Gd-SLs) on MR imaging.

Materials And Methods: Three Gd-DTPA liposomal nanoparticles were prepared in our trial: liposomes entrapping Gd-DTPA (Gd-SLs), Gd-SLs conjugated to immunoglobulins (IgG-Gd-SLs) and CD105-Gd-SLs. Forty glioma-bearing rats were randomized into four groups: (a) Gd-DTPA; (b) Gd-SLs; (c) IgG-Gd-SLs; (d) CD105-Gd-SLs.

Establishing models of portal vein occlusion and evaluating value of multi-slice CT in hepatic VX2 tumor in rabbits.

Aim: To establish models of portal vein occlusion of hepatic VX2 tumor in rabbits and to evaluate the value of multi-slice CT.

Methods: Forty New Zealand rabbits were divided into 4 groups according to digital table: Immediate group (group A; transplantation of tumor immediately after the portal vein occlusion), 3-wk group (group B; transplantation of tumor at 3 wk after the portal vein occlusion), negative control group (group C) and positive control group (group D), 10 rabbits in each group. Hepatic VX2 tumor was transplanted with abdominal-embedding inoculation immediately after the portal vein occlusion and at 3 wk after the portal vein occlusion.
