To prospectively determine the sonographic findings of nodular hyperplasia thyroid, to compare these with reported associated malignancy, and assess interobserver reliability.Seventy thyroid nodules were scanned, then biopsies performed under guidance fine-needle cytologic analysis; in all cases images reviewed by 2 experienced radiologists without knowledge clinical outcome. Findings malignancy specifically assessed. Interobserver agreement between expert secondary readers for each finding...
The purpose of our retrospective study was to evaluate the sensitivity and negative predictive value percutaneous biopsy renal masses stratified by clinical setting size mass.We categorized 115 consecutive biopsies in 113 patients into four settings three groups mass sizes. were computed (with 95% confidence intervals [CI]) for each group.For all procedures (n = 115), 90% (95% CI, 81-95%) 64% 44-81%), respectively. For with a known malignancy who presented 55), 78-96%) 38% 10-74%), no...
The multitargeted tyrosine kinase inhibitor sorafenib is used for the treatment of advanced-stage renal cell carcinoma. However, safety and efficacy this agent have yet to be evaluated in preoperative period, where there may potential advantages including tumor downstaging. This prospective trial evaluates feasibility setting.Thirty patients with clinical stage II or higher masses, selected based on their candidacy nephrectomy, underwent sorafenib. Toxicities, surgical complications,...

Our objective was to use a combination of axial MR source images and three-dimensional (3D) models describe the anatomy normal pelvic floor in young nulliparous women measure volume levator ani.Ten healthy female volunteers (average age, 27 years) underwent T2-weighted imaging pelvis. Three-dimensional color-coded bones organs three major components ani--puborectalis, iliococcygeus, coccygeus--were created. Source were used muscle width signal intensity identify ligamentous structures. Using...
Pelvic floor weakness is common in middle-aged and elderly parous women often associated with stress incontinence, uterine prolapse, constipation, incomplete defecation. Most patients incontinence minimal pelvic can be treated based on physical examination basic urodynamic findings. However, symptoms of multicompartment involvement for whom a complex repair planned or who have undergone previous repairs, magnetic resonance (MR) imaging useful preoperative planning tool. The MR evaluation...

In Brief OBJECTIVES: To use static and dynamic magnetic resonance imaging (MRI) to compare dimensions of the bony pelvis soft tissue structures in a sample African-American white women. METHODS: This study used data from 234 participants Childbirth Pelvic Symptoms Imaging Study, cohort 104 primiparous women with an obstetric anal sphincter tear, 94 who delivered vaginally without recognized tear 36 underwent by cesarean delivery labor. Race was self-reported. At 6–12 months postpartum, rapid...
Study Type – Therapy (cohort) Level of Evidence 2b OBJECTIVE To evaluate the clinicopathological efficacy neoadjuvant erlotinib (an epidermal growth factor receptor, EGFR, inhibitor) for invasive bladder cancer in patients undergoing radical cystectomy (RC) as despite definitive surgical therapy, only half RC will have long‐term disease‐free survival, and effective adjunctive therapies, especially using agents with lower toxicity, would be a significant advance treatment cancer. PATIENTS AND...
The purpose of this study was to determine whether unenhanced helical CT alone can be used for diagnosis and treatment planning patients with obstructing ureteral stones.Medical records 100 stones a clearly discernible clinical outcome who had undergone were reviewed the number urography procedures results excretory urograms performed within 72 hr CT. scans then by two radiologists six findings: in-plane stone diameter, z-axis location stone, periureteral stranding, hydronephrosis,...
Abstract Studies have shown that tumor angiogenesis is an essential process for growth, proliferation and metastasis. Also, important prognostic factor of clear cell renal carcinoma (ccRCC), as well a in guiding treatment with antiangiogenic agents. Here, we attempted to find the associations between radiomic imaging features from PET/MRI. Specifically, sparse canonical correlation analysis was conducted on 3 feature datasets (i.e., features, microvascular density (MVD), vascular endothelial...
To develop and evaluate domain-specific pretrained bidirectional encoder representations from transformers (BERT) models in a transfer learning task on varying training dataset sizes to annotate larger overall dataset.The authors retrospectively reviewed 69 095 anonymized adult chest radiograph reports (reports dated April 2020-March 2021). From the cohort, 1004 were randomly selected labeled for presence or absence of each following devices: endotracheal tube (ETT), enterogastric (NGT,...
Abstract Purpose: To describe the inter‐ and intra‐operator reliability of segmentations female pelvic floor structures. Materials Methods: Three segmentation specialists were asked to segment out structures in 20 MR datasets on three separate occasions. The STAPLE algorithm was used compute intra‐segmenter agreement each organ dataset. computed sensitivity, specificity, positive predictive values (PPV) for repeatability. These parameters analyzed using intra‐class correlation analysis....
Patients with chronic kidney disease are at increased risk of cystic that requires imaging monitoring in many cases. However, these same patients often have contraindications to contrast-enhanced computed tomography and magnetic resonance imaging. This study evaluates the accuracy ultrasound (CEUS), which is safe for disease, characterization lesions without disease. We performed CEUS on 44 patients, both indeterminate or suspicious (both solid). Two masked radiologists categorized using...
