[Initial experience of 640-slice CT coronary angiography in pacemaker patients].

Objective: To investigate the feasibility and image quality of coronary artery angiography with 640-slice CT system in the pacemaker patients.

Methods: ECG-triggered 640-slice CT coronary angiography was performed in 16 pacemaker patients. Image quality of the fifteen coronary segments and metal-related artifact originating from pacemaker were assessed by two experienced radiologists in consensus.

[Application value of FS-3D-FISP sequence in the diagnosis of ankle cartilage injury].

Objective: To compare several sequences of MRI and arthroscopy for detecting the ankle articular cartilage lesions and to evaluate the clinical outcome of special sequence of FS-3D-FISP.

Methods: Forty patients (41 ankles) with iterative ankle pain who were scheduled for arthroscopy underwent MR scanning, including FS-3D-FISP, FSE T2WI and FSE PDWI sequences. The results of each sequence were then compared with the arthroscopic findings.
