OBJECTIVE To evaluate the diagnostic efficacy of thin-slice (1 mm) axial proton density-weighted (PDW) MRI of the knee for meniscal tear detection and classification. METHODS We prospectively assessed pre-operative MR images of 58 patients (41 males, 17 females; age range 18-62 years) with arthroscopically confirmed meniscal tear. First, we evaluated the(More)
The aim of this study was to investigate the effect of stent cell geometry on midterm results of carotid artery stenting (CAS). One hundred fifty-five patients underwent CAS between February 2010 and December 2012. Ninety-one open- and 84 closed-cell stents were used in this non-randomized, retrospective study. Periprocedural complications were defined as(More)
The treatment options for high risk acute pulmonary embolism (PE) patients with failed systemic thrombolytic treatment (STT) is limited. The clinical use of catheter directed thrombolysis with the EkoSonic Endovascular System (EKOS) in this population has not been evaluated before. Catheter directed thrombolysis is an effective treatment modality for high(More)
Endovascular treatment of wide-necked bifurcation aneurysms may be challenging. The waffle-cone technique can be used in these aneurysms in case of acute angulation between parent artery and distal artery of the aneurysm. Solitaire® stent (Ev3, Irvine, CA, USA) has the significant advantage of mitigating the potential complication risks. This study reports(More)
To evaluate long-term clinical follow-up results of implanting subcutaneous port catheters (SPCs) on ipsilateral or contralateral with mastectomy side in patients with axillary lymph node dissection. A total of 73 patients composed of ipsilateral (34 catheters) and contralateral (39 catheters) groups, with SPCs were included. All patients had lumpectomy or(More)
Endovascular treatment of wide-necked bifurcation aneurysms can be challenging, despite improvements in endovascular techniques. Y stent-assisted coiling is one such technique, but this may not be technically feasible, especially in cases of acute angulation between the proximal and distal parent arteries, and may require use of “modified Y-configured(More)
The aim of this study was to analyze variations in the morphological features of the subparietal sulcus (SPS) and to investigate interhemispheric and gender differences in these variations using multiplanar reconstructed (MPR) magnetic resonance (MR) images. Two hundred subjects with normal cranial MR imaging, including high-resolution T1-weighted(More)
