PURPOSE: To evaluate contrast agent–enhancement patterns in hepatic hemangiomas, metastases, and hepatocellular carcinomas (HCCs) at pulse-inversion harmonic ultrasonography (US) with a microbubble agent. MATERIALS AND METHODS: Twenty hemangiomas 20 patients 41 malignant tumors 23 (33 metastases eight HCCs) were evaluated US. US images obtained before injection every 10–15 seconds after of 4-g bolus (300 mg/mL) SH U 508A (a agent) for 5 minutes. The contrast-enhancement 61 lesions assessed....
Background: The outcomes of medial meniscal allograft transplantation (MMAT) combined with high tibial osteotomy (HTO) compared isolated MMAT remain unclear. Purpose: To compare the clinical and radiological results HTO MMAT. Study Design: Cohort study; Level evidence, 3. Methods: This retrospective study included 42 consecutive patients, who were divided into group M (isolated MMAT; n = 22) H (MMAT a varus angle >3°; 20). Group differences in subjective knee scores, isokinetic muscle...
Background: Despite numerous studies examining subjective clinical scores after meniscal allograft transplantation (MAT), research focusing specifically on functional measures is lacking. Purpose: To evaluate the serial changes in isokinetic muscle strength and dynamic balance during first postoperative year lateral MAT (LMAT). Study Design: Cohort study; Level of evidence, 3. Methods: A total 55 patients who underwent LMAT assessment using Lysholm International Knee Documentation Committee...
The present study was undertaken to evaluate the effectiveness of transforaminal epidural steroid injection (TFESI) with using a preganglionic approach for treating lumbar radiculopathy when nerve root compression located at level supra-adjacent intervertebral disc.The medical records patients who received conventional TFESI our department from June 2003 May 2004 were retrospectively reviewed. performed in total 13 cases exiting root, which disc (the group). Since 2004, we have (for example,...
MRI analysis of subtalar ligaments in the tarsal sinus has not been well performed. We retrospectively investigated appearance using 3D isotropic and compared imaging findings between patients with instability (STI) controls. Preoperative MRIs 23 STI treated arthroscopic reconstruction were to age- sex-matched control subjects without STI. Thickness width anterior capsular ligament (ACL) interosseous talocalcaneal (ITCL) as thickness calcaneofibular (CFL) talofibular (ATFL) measured....
Objective: To evaluate the usefulness of time-resolved contrast enhanced magnetic resonance angiography (4D MRA) after stent-assisted coil embolization by comparing it with time flight (TOF)-MRA.Materials and Methods: TOF-MRA 4D MRA were obtained 3T MRI in 26 patients treated (Enterprise:Neuroform = 7:19).The qualities rated on a graded scale 0 to 4. We classified completeness endovascular treatment into three categories.The degree quality visualization stented artery was compared between...
Objective: The purpose of this study was to examine the effects computed tomographic (CT) parameters on metal artifact reduction in multidetector CT (MDCT) using a quantitative 3-dimensional (3D) measurement volume. Methods: A steel-based plate and screw were implanted femora 3 porcine thigh specimens. specimens examined 16-slice MDCT with 7 different combinations acquisition that consisted kilovolt (peak) (kV[p]) effective milliampere-seconds (mAs): 120 100; 300; 500; 1000; 140 500 under...
There is considerable debate on the recovery of rotator cuff muscle atrophy after repair.To evaluate serial changes in supraspinatus volume repair by using semiautomatic segmentation software and to determine relationship with functional outcomes.Case series; Level evidence, 4.Seventy-four patients (mean age, 62.8 ± 8.8 years) who underwent arthroscopic obtained 3 consecutive (preoperatively, immediately postoperatively, later postoperatively [≥1 year postoperatively]) magnetic resonance...
The purpose of this study was to assess the differences between subtalar instability (STI) and lateral ankle (LAI) focusing on ligaments using 3-dimensional (3D) isotropic magnetic resonance imaging (MRI).Preoperative MRIs 10 patients with STI who failed nonoperative treatment consequently underwent arthroscopic reconstruction were compared preoperative 23 LAI ligament repair or reconstruction. Dimensions anterior capsular (ACL), interosseous talocalcaneal (ITCL), calcaneofibular (CFL),...
Objective: This study was designed to determine the optimal mixture ratio of gadolinium and iodinated contrast agent for simultaneous direct MR arthrography CT arthrography. Materials Methods:An in vitro performed utilizing mixtures at six different concentrations (0.625, 1.25, 2.5, 5.0, 10 20 mmol/L) seven (0, 12.5, 25, 37.5, 50, 75 92-99.9%).These were placed tissue culture plates, then imaged with (with T1-weighted sequences, proton-density sequences T2-weighted sequences).CT numbers...
