Introduction and purpose VISA-P questionnaire assesses to severity of symptoms and treatment effects in athletes with patellar tendinopathy. The purpose of this study was to translated VISA-P questionnaire into Turkish language and to determine its validity and reliability.MethodsThe English version of VISA-P questionnaire was translated into Turkish according to the internationally recommended guidelines. Test–retest reliability was determined on 89 participants with time interval 24 h. To determine validity of Turkish VISA-P, 31 (17 male, 14 female) healthy students, 34 (20 male, 14 female) patients with patellar tendinopathy (diagnosed by physical examination and ultrasonography) and 24 (16 male, 8 female) volleyball players (at risk populations) were completed VISA-P-Tr. Internal consistency was determined with Cronbach’s alpha. Intraclass correlation coefficients (ICCs) were calculated to analyse test–retest reliability. To assessment of discrimination, VISA-P-Tr scores compared all groups using the Mann–Whitney-U test.Results The VISA-P-Tr questionnaire showed good test–retest reliability (The Cronbach’s alpha was 0.79 and 0.78 respectively and ICC was 0.96). The VISA-P-Tr score (mean ± SD) were 93.7 ± 8.9 and 94.0 ± 8.1 for healthy students, 81.1 ± 13.7 and 80.7 ± 13.4 for volleyball players, 58.8 ± 12.1 and 58.5 ± 11.0 for athletes with patellar tendinopathy.ConclusionThe translated Turkish version of VISA-P has good internal consistency and good reliability and validity. Therefore VISA-P-Tr is useful to evaluate symptoms and follow the treatment effect in athletes with patellar tendinopathy.

CT-guided percutaneous transthoracic biopsy of the lung is a well-established method for diagnosis of pulmonary lesions yielding a diagnostic accuracy of 71%-95% (1-5), with pneumothorax being the most common complication varying between 17% and 26% (5-7). Currently coaxial technique is more commonly employed than the non-coaxial technique. The risk of pneumothorax may play a decisive role on this preference. Theoretically, fewer pleural passes means less risk of pneumothorax with the coaxial technique. However, introduction of relatively large bore needles are needed in the coaxial technique, which is a known risk factor for the development pneumothorax (8,9). To the best of our knowledge, there are only a few studies on CT-guided transthoracic fine needle aspiration (FNA) biopsies with non-coaxial technique on large patient populations (10, 11).The purpose of this retrospective study was to evaluate the diagnostic accuracy and safety of CT-guided transthoracic biopsy of pulmonary lesions with FNA using the non-coaxial technique. Methods PatientsThe institutional review board approved this retrospective study protocol and waived informed consent.CT images and biopsy records were retrospectively evaluated in 442 patients (346 males [78.3%] and 96 females [21.7%]; mean age, 64±10.8 years; range, 22-89 years) who underwent CT-guided transthoracic FNA of pulmonary lesions between July 2011 and June 2015. Bronchoscopy or transbronchial biopsies were nondiagnostic or not feasible in these patients.Exclusion criteria for the procedure were lesions <5 mm in maximum diameter, lesions suspected to be of vascular origin, uncorrectable coagulopathy (international normalized ratio ≥1.5, platelet count <50,000 K/UL), patients who were unable to maintain the appro- I N T E R V E N T I O N A L R A D I O LO G Y O R I G I N A L A R T I C L E PURPOSEWe aimed to evaluate the diagnostic accuracy and safety of computed tomography (CT)-guided biopsy of pulmonary lesions with fine needle aspiration (FNA) using non-coaxial technique. METHODSWe analyzed 442 patients who underwent CT-guided lung biopsy with FNA and non-coaxial technique to determine the diagnostic outcomes, complication rates, and independent risk factors for diagnostic failure and pneumothorax. RESULTSDiagnostic accuracy, sensitivity, and specificity were 97.6%, 97.3%, and 100%, respectively. Age and >35 mm lesion size were significant risk factors for diagnostic failure. The rates of pneumothorax and chest tube placement were 19% and 2.9%, respectively. Middle and lower lobe location, lesion to pleura distance >7.5 mm, and >45° needle trajectory angle were significant risk factors for pneumothorax. CONCLUSIONCT-guided FNA of pulmonary lesions with non-coaxial technique is a safe and reliable method with a relatively low pneumothorax rate and an acceptably high diagnostic accuracy.

Background Paraspinal musculature (PSM) is increasingly recognized as a contributor to low back pain (LBP), but with conventional MRI sequences, assessment is limited. Chemical shift encoding‐based water–fat MRI (CSE‐MRI) enables the measurement of PSM fat fraction (FF), which may assist investigations of chronic LBP. Purpose To investigate associations between PSM parameters from conventional MRI and CSE‐MRI and between PSM parameters and pain. Study Type Prospective, cross‐sectional. Population Eighty‐four adults with chronic LBP (44.6 ± 13.4 years; 48 males). Field Strength/Sequence 3‐T, T1‐weighted fast spin‐echo and iterative decomposition of water and fat with echo asymmetry and least squares estimation sequences. Assessment T1‐weighted images for Goutallier classification (GC), muscle volume, lumbar indentation value, and muscle‐fat index, CSE‐MRI for FF extraction (L1/2–L5/S1). Pain was self‐reported using a visual analogue scale (VAS). Intra‐ and/or interreader agreement was assessed for MRI‐derived parameters. Statistical Tests Mixed‐effects and linear regression models to 1) assess relationships between PSM parameters (entire cohort and subgroup with GC grades 0 and 1; statistical significance α = 0.0025) and 2) evaluate associations of PSM parameters with pain (α = 0.05). Intraclass correlation coefficients (ICCs) for intra‐ and/or interreader agreement. Results The FF showed excellent intra‐ and interreader agreement (ICC range: 0.97–0.99) and was significantly associated with GC at all spinal levels. Subgroup analysis suggested that early/subtle changes in PSM are detectable with FF but not with GC, given the absence of significant associations between FF and GC (P‐value range: 0.036 at L5/S1 to 0.784 at L2/L3). Averaged over all spinal levels, FF and GC were significantly associated with VAS scores. Data Conclusion In the absence of FF, GC may be the best surrogate for PSM quality. Given the ability of CSE‐MRI to detect muscle alterations at early stages of PSM degeneration, this technique may have potential for further investigations of the role of PSM in chronic LBP.
