Acoustic radiation force impulse imaging has high sensitivity and specificity for differentiating parathyroid adenomas from benign and malignant thyroid nodules. As an adjunctive tool, it can help distinguish parathyroid adenomas from thyroid nodules, including posteriorly located nodules.

Sonoelastography is a novel imaging technique that enables us to evaluate the stiffness of adnexal lesions. The accurate discrimination of endometriomas and hemorrhagic ovarian cysts is important for avoiding unnecessary surgical procedures. ARFI imaging has a high sensitivity and specificity for distinguishing endometrioma from hemorrhagic ovarian cysts.

Bu çalışmada COVID-19 tanısı alan hastaların toraks bilgisayarlı tomografi (BT) sonuçlarını inceleyip, tipik ve atipik bulguları literatür eşliğinde sunmayı amaçladık.Araçlar ve Yöntem: Hastanemize mart ve nisan aylarında başvuran ve reverse transkriptaz-polimeraz zincir reaksiyonu (RT-PZR) ile COVID-19 tanısı alan hastaların toraks BT'leri retrospektif olarak değerlendirildi. Akciğer parankim bulgularından buzlu cam sahaları, konsolidasyon, vasküler genişleme, fibrozis, nodül, septal kalınlaşma (crazy paving), ters halo, plevral effüzyon ve mediastinal LAP bulguları araştırıldı. Parankimdeki tutulum yerine göre bilateral-unilateral, periferik-santral, üst-orta-alt loblardaki odak sayılarına göre lezyonların dağılımı değerlendirildi.Bulgular: PCR pozitif olan 53 hastanın (ortalama yaş 48,38±20,97) 14'ünde (% 26) toraks BT'de bulgu yoktu. BT'de bulgusu olan 39 hastada (%74), tipik bulgulardan buzlu cam sahası (%85), konsolidasyon (%56), buzlu cam ve konsolidasyon birlikteliği (%59), vasküler genişleme (%28) izlendi. Atipik bulgulardan nodül (%20), septal kalınlaşma (%30), fibrozis (%10), plevral efüzyon (%8), hava bronkogramı (%18), ters halo bulgusu (%5) saptandı. Hastalarımızda mediastinal LAP saptanmadı. Toraks BT'de bilateral, orta ve alt zonlarda periferik yerleşimli multifokal odaklar tipik tutulum şekliydi. 14 hastada toraks BT negatif olup herhangi bir bulguya rastlanmadı.Sonuç: Toraks BT, COVID-19 hastaları için tanıya yardımcı çok önemli bir yöntem olup parankim tutulumunun tipik ve atipik bulgular şeklinde kategorize edilerek değerlendirilmesi tanı sürecini kolaylaştırabilir.

SummaryBackgroundUterine lipoleiomyoma is a rare and specific type of leiomyoma.Case ReportA 60-year-old postmenopausal woman presented with abdominal pain. Her pelvic ultrasound demonstrated a normal- sized uterus with a well- circumscribed, heterogeneous mass located in the anterior corpus. A pelvic MRI revealed a mass including hyperintense areas on T1-weighted images and hypointense on fat-suppressed T1-weighted images, compatible with lipoleiomyoma.ConclusionsUterine lipoleiomyomas are often misdiagnosed pre-operatively and it is important to distinguish leiomyomas from other tumors for prevention from supererogatory surgery. Imaging plays an important role for the exact differentiation.

Background Changes in optic nerve vascularity are observed in many diseases. Superb microvascular imaging (SMI) has the potential to become the method of choice for detecting microvasculature in the optic nerves. Purpose To evaluate optic nerve vascularity in healthy individuals through power Doppler sonography (PDUS) and SMI. Material and Methods Twenty-seven healthy patients with 54 eyes were prospectively evaluated. The duration of the examination for optic nerve vascularity lasted until the posterior ciliary artery blood supply was observed in PDUS and SMI. The visibility of vascularity, as well as the ratio of the vascular structures to the optic nerves (vascular index [VI]), was evaluated. Results Fifty-four eyes were evaluated from a total of 27 patients (mean age = 49.0 ± 19.42 years). The VI value for the right optic nerve was 29.58 ± 4.00 while for the left optic nerve, it was 31.21 ± 3.52. Vascularity was clearly observed in both eyes (n = 54) in all 27 cases in the evaluation performed with the SMI technique. However, with the power Doppler examination, vascular flow was not observed in 14 right eyes and in 10 left eyes within the specified timeframe. Conclusion The results indicate that imaging of vascular structures can be done faster and better with SMI than PDUS examination. The normal VI values may provide important information about the blood supply of the optic nerve, which is of relevance in orbital pathologies and many systemic conditions.

Totally implantable venous access systems are widely used in oncology; however, their complications are extremely common whic h, sometimes, require device removal, thereby, leading to delayed chemotherapy and infusion therapies. In this study, we aimed t o investigate the immediate, early, and late complications of venous port implantation in our oncology patients. A total of 219 consecutive cancer patients (111 males, 108 females; mean age: 56.9 years; range: 1 to 81 years) were retrospe ctively analyzed between January 2013 and June 2014. A total of 220 ultrasound-and fluoroscopy-guided totally implantable venous port systems were implanted through the right or left internal jugular vein access. The mean follow-up was 83.7 (range: 2 to 410) days. Overall c omplication rate was 8.6% (19/220). Eight devices in seven patients were removed due to complications. Two ports were removed in one patient. The complications which required port removal were compromised port-related bloodstream infection (n=5), central venous thrombosis (n=3), and catheter thrombosis (n=1). No major complication or no mortality associated with the port implantation was seen during follow-up. Totally seven immediate complications including local hematoma (n=2), catheter tip retraction (n=2), pain (n=1), catheter loop formation (n=1), catheter malposition (n=1), two early complications (n=2; 1 wound dehiscence, and 1 wound infection), and 10 late complications including catheter-related blood stream infection (n=5), central venous thrombosis (n=3), catheter thrombosis (n=1), and tunnel hematoma (n=1) occurred. Low incidence of complications suggest ultrasound-and fluoroscopy-guided venous port implantation is a safe and reliable method for long-term venous access

Çalışmamızın amacı klinik tanı ile uyumlu acil servise giriş yapan hastaların çektikleri beyin bilgisayarlı tomografisi sonuçlarını göstermektir. Gereç ve Yöntemler: Bu çalışma, acil servisten 1 Ocak 2018 ile 30 Haziran 2018 tarihleri arasında bilgisayarlı tomografi taraması geçirmiş, yaş ve cinsiyet arasında bir ayrım gözetmeyen tüm hastaları içermektedir. Hastalar acil servise baş ağrısı, baş dönmesi, trafik kazası ve serebrovasküler olay (SVO) gibi şikayetleri ile kabul edildi. Hastaların yaş, cinsiyetleri ve beyin tomografi bulgularının sayı ve yüzde bulguları analiz edildi. Bulgular: Toplam altı ayda, 16428 hastanın 3975'inin beyin BT görüntüsü vardı. Çalışmamızda erkek hasta 2018 (% 51), kadın hasta 1957 (% 49) ve yaş ortalaması 45,40 ± 24 idi. Baş ağrısı, baş dönmesi, travma ve SVO şikayeti ile acilden radyolojiye sevk edilen hastalar dahil edildi. Çalışmada, rapor bulgularının 735'si (% 19) anlamlıydı ve 3240 (% 81) hastada önemsizdi. Sonuç: Rapor bulgularının büyük ölçüde temiz olması, bu kadar çok BT görüntüsünün neden yapıldığı sorusunu ortaya koymaktadır.
