Publication Metadata only Evaluation of sacroiliac joint MRI for pelvic venous congestion signs in women clinically suspected of sacroiliitis(SAGE PUBLICATIONS LTD, 2017) YOLDEMİR, AHMET TEVFİK; Cimsit, Canan; Yoldemir, Tevfik; Tureli, Derya; Aribal, Mustafa ErkinBackground: Pelvic congestion syndrome (PCS) is a commonly overlooked condition which is a potential cause of chronic pelvic pain. Magnetic resonance imaging (MRI) of the sacroiliac joint (SIJ) may demonstrate unexpected conditions that can mimic sacroiliitis (SI). Awareness of MRI-defined pelvic venous congestion (PVC) may help in identifying PCS, where vascular abnormality may be the sole manifestation of SIJ pain. Purpose: To detect incidental MRI-defined PVC in patients who underwent SIJ-MRI for presumed SI and define the variance of its incidence. Material and Methods: A total of 870 women who underwent SIJ-MRI were retrospectively evaluated. Incidental findings of PVC and other genitourinary and musculoskeletal system disorders were documented. Results: Of the 774 included patients, 37% demonstrated incidentally detected imaging findings related to the genitourinary system, musculoskeletal system, and PVC. The prevalence of MRI-defined PVC signs was higher in patients without SI than with SI. The prevalence of musculoskeletal disorders was higher in patients with SI whereas prevalence for genitourinary disorders was similar. Binary logistic regression analysis revealed a statistically significant correlation between SI-PVC and SI-genitourinary disorders but not between SI-musculoskeletal disorders pairs (P = 0.001, 0.001, and 0.057> 0.05). The probability of observing SI in SIJ-MRI is positively correlated with the absence of PVC or genitourinary disorders. Conclusion: Patients who underwent MRI for presumed SI demonstrated incidental PVC as well as other genitourinary and musculoskeletal findings. An awareness of these imaging findings can help identify PVC and may draw clinicians' attention to the possibility of PCS.Publication Metadata only Thyroid fine needle aspiration biopsy: Do we really need an on-site cytopathologist?(ELSEVIER IRELAND LTD, 2014) TÜRELİ, DERYA; Cengic, Ismet; Tureli, Derya; Ahiskali, Rengin; Bugdayci, Onur; Aydin, Hilal; Aribal, ErkinPurpose: The aim of this single center study is to evaluate the effectiveness of performing ultrasound-guided thyroid fine-needle aspiration biopsies (FNAB) performed by the radiologist alone without an on-site cytopathologist. Materials and methods: In this prospective randomized study, 203 patients with single nodules measuring 10 mm or more underwent ultrasound-guided FNAB: 102 patients underwent FNAB performed by the radiologist accompanied by a cytopathologist (control group); 101 patients underwent FNAB by the radiologist alone (study group). In both groups biopsy time, specimen adequacy ratio, total aspiration number, cytopathologist's cytological diagnosis time (t1), cytopathologist's total time consumption (t2) were evaluated. Results: Mean total biopsy time was 8.74 +/- 2.31 min in the study group and was significantly shorter than the control group's 11.97 +/- 6.75 min (p = 0.004). The average number of aspirations per patient in the study group was 4.00 +/- 0; compared to the control group's 3.56 +/- 1.23 this was significantly higher (p = 0.001). t1 of the study group was 307.48 +/- 226.32 s; compared to 350.14 +/- 247.64 s in the control group, there was no statistically significant difference (p = 0.137). t2 of the study group was 672.93 +/- 270.45 s; compared to the control group (707.03 perpendicular to 258.78 s) there was no statistically significant difference (p = 0.360). Diagnostic adequacy of aspirated specimens was reassessed in the pathology laboratory. In the study group, 84 out of 101 aspirations and in the control group 89 out of 102 aspirations was determined as adequate with no statistically significant difference (p = 0.302). Conclusions: We believe that in centers where a cytopathologist is not available, ultrasound-guided thyroid FNAB can be adequately performed by an experienced radiologist who was effectively trained in smear preparation.

Purpose: To evaluate the effects of nodule volume and extent of cystic degeneration on total biopsy time and number of aspirations required for obtaining an adequate specimen. Material and Methods: A total of 510 patients underwent FNAB by a single radiologist accompanied by a cytopathologist who immediately assessed each sample for specimen adequacy. All sampled nodules were single and had one maximum diameter > 10 mm. Nodule volumes and cystic degeneration ratios were calculated prior to the intervention. Aspirations were repeated until the cytological material was deemed adequate by the cytopathologist; the number of aspirations and total biopsy time were then recorded. Results: Nodule volumes did not have significant effect on neither number of aspirations necessary for achieving specimen adequacy (P > 0.05) nor total biopsy time (r = -0.148 with P = 0.001). Predominantly cystic nodules, compared to predominantly solid nodules, required more sampling per nodule (4.58 +/- 1.11 vs. 3.44 +/- 1.19 aspirations, P = 0.001) and longer total biopsy time (16.40 +/- 6.19 vs. 11.15 +/- 6.18 min, P = 0.001). Conclusion: Predominantly cystic nodules require allocation of more time for biopsy. To ensure specimen adequacy when immediate specimen evaluation by an on-site cytopathologist is not possible, four samples from predominantly solid nodules and five passes through predominantly cystic nodules are required.
