OBJECTIVES: To assess the correlation between inflammatory sonographic findings (grayscale synovial hypertrophy and power Doppler) and clinical and functional assessments in hand osteoarthritis (symptomatic interphalangeal joints) and to correlate the intraobserver and interobserver reliability of these findings. METHODS: A prospective double-blind study of 60 interphalangeal joints was conducted. The joints were assessed 6 times per year by clinician and sonographer observers...

Multiparametric testicular ultrasound and magnetic resonance imaging (MRI) findings were analyzed in a series of 10 infertile asymptomatic men presenting with pathologically confirmed burned-out testicular tumors. Color/power Doppler ultrasound (CDUS), shear wave elastography (SWE), contrast-enhanced ultrasonography (CEUS), and MRI were performed on 10, 5, 6, and 7 patients, respectively. All lesions appeared as a hypoechoic and hypovascular nodular area at CDUS, SWE, CEUS CDUS, and CEUS (if performed). Shear wave elastography showed a stiffer nodular area compared with the surrounding/contralateral tissues (13 versus 2 kPa); MRI revealed a well-delineated nodular area in hypointense signal on T2, a high apparent diffusion coefficient value, and a lack of enhancement...

We retrospectively collected cases of surgically proven extradigital glomus tumor (EDGT) and reviewed their demographic, clinical, and sonography features. A total of 18 single, subcutaneous EDGTs were gathered. All but one were located in the extremities. EDGTs typically appear as a small, hypoechoic, homogeneous, or slightly inhomogeneous, well-delimited nodule, disposed horizontally and painful under probe pressure. Intranodular vascularization is always present. Feeding artery and efferent vein are typical but inconstant findings...

BACKGROUND: Varicocele, one of the most common causes of sperm abnormalities in men, is the dilation of the testicular vein (the pampiniform venous plexus) by more than 2 mm. Ultrasonography is the primary imaging procedure for varicocele diagnosis. The venous diameter is evaluated using B-mode sonography, and venous reflux is assessed using color Doppler sonography. OBJECTIVES: In this study, we investigated the association of ultrasound findings with sperm parameters in patients with varicocele...

BACKGROUND: Ovarian thecoma-fibroma groups (OTFG) are uncommon sex cord-stromal neoplasms. The objective of the study was to demonstrate clinical and sonographic features of OTFG and compare with surgical histopathology. METHODS: A total of 61 patients with surgically proven OTFG were enrolled in this retrospective study to demonstrate its clinical and sonographic features and to compare with pathological findings. Gray scale and color Doppler sonography were performed presurgically with either transabdominal or transvaginal approach to image pelvic structures and lesions...

Pyomyositis in the neck has rarely been described. We present the sonographic findings in a case of pyomyositis of the sternocleidomastoid muscle. A 62-year-old man with poorly controlled diabetes presented with an induration of the neck and fever. On gray-scale sonography, a part of the sternocleidomastoid muscle appeared swollen and contained irregularly shaped hypoechoic areas. Power Doppler imaging showed increased vascularity in the muscle. Sonographic-guided aspiration confirmed abscesses in the sternocleidomastoid muscle...

OBJECTIVES: The purpose of this study was to evaluate pregnancies with isolated short fetal femur and humerus on second-trimester sonography. Short fetal long bones are known to be associated with aneuploidy and structural anomalies. In this study, we wanted to show the risk of adverse pregnancy outcomes in euploid and nonanomalous pregnancies. METHODS: Singleton pregnancies with short femur and humerus were included. Pregnancies with normal fetal bone lengths and age-matched mothers were selected as controls...

OBJECTIVES: The purpose of this study was to evaluate differences in uterine artery blood flow parameters and pregnancy outcomes, if any. An investigation was conducted to determine the effects of low-dose aspirin on uterine artery blood flow indices in patients with recurrent pregnancy loss.

BACKGROUND: Rheumatoid arthritis (RA) commonly involves the knee joint in up to 30% of patients. Musculoskeletal ultrasound enables the skilled clinician to easily assess disease activity. OBJECTIVE: To evaluate the sensitivity to change of the sonography score of large joints in Rheumatology (SOLAR) for different treatments of knee arthritis in RA. METHOD: Joints were assessed by ultrasound at 4 visits. Laboratory, immunological and clinical parameters were recorded...

Transcranial Doppler (TCD) sonography is a frequently employed technique for quantifying cerebral blood flow by assuming a constant arterial diameter. Given that exercise increases arterial pressure by sympathetic activation, we hypothesized that exercise might induce a change in the diameter of large cerebral arteries. Middle cerebral artery (MCA) cross-sectional area was assessed in response to handgrip exercise by direct magnetic resonance imaging (MRI) observations. Twenty healthy subjects (11 female) performed three 5 min bouts of rhythmic handgrip exercise at 60% maximum voluntary contraction, alternated with 5 min of rest...

OBJECTIVES: The purpose of this study was to examine whether the maternal renal interlobar vein impedance index as assessed by first-trimester sonography is able to predict the later development of hypertensive disorders of pregnancy. METHODS: Venous Doppler parameters of both maternal kidneys were studied in 214 pregnant women at gestational ages of 11 weeks to 13 weeks 6 days. Patients were classified according to outcomes related to hypertensive disorders. Detection rates and areas under receiver operating characteristic curves were determined for the maternal renal interlobar vein impedance index as a first-trimester predictor of preeclampsia and gestational hypertension...

AIM: To optimize diagnostics and treatment of cystic liver tumors. MATERIAL AND METHODS: The analysis included outcomes of 46 patients with liver cystic tumors. RESULTS AND DISCUSSION: The use of abdominal Doppler-sonography (37 patients), abdominal contrast-enhanced CT (44 patients) and MRI of abdominal cavity with MR-cholangiography (24 patients) defined radiological semiotics of cystic liver diseases. The most important features of cystic tumors are intraluminal septums with blood flow (82% of patients), solid component (6...

BACKGROUND: Doppler sonography is a type of sonography used for imaging the blood flow in the vessels and heart. This technique uses ultrasound waves with high frequency. In some patient candidates for venous graft, the identification of the suitable vein is not possible with clinical examination. OBJECTIVE: This study compared the effects of preoperative color Doppler sonography of lower extremity veins on the postoperative outcomes of saphenectomy. METHODS: This randomized clinical trial was conducted on 100 candidates of an off-pump coronary artery bypass graft (CABG) hospitalized in Afshar Hospital in Yazd in 2015...

Only a few cases of Turner syndrome (TS) with ischemic stroke have been reported. Various arteriopathies of the cerebral arteries, including fibromuscular dysplasia, congenital hypoplasia, moyamoya syndrome, and premature atherosclerosis have been assumed to be the cause of ischemic stroke in TS. There has been no case report of a TS patient presenting with an embolic stroke pattern without any cerebral arteriopathy. A 28-year-old woman with TS was referred to our hospital because of abnormal brain magnetic resonance imaging (MRI) findings...

Gallbladder varices are a rare form of collateralization that develop in patients with portal hypertension. We present here a case of gallbladder varices accurately diagnosed by contrast enhanced CT imaging of the abdomen and confirmed by Color Doppler Sonography. A 76-year-old patient with hepatocellular carcinoma developed portal vein thrombosis due to tumor extension during the course of treatment and was incidentally discovered to have gallbladder varices. While most commonly asymptomatic, gallbladder varices are associated with increased risk of massive bleeding, either spontaneously or during cholecystectomy...

Solitary fibrous tumor (SFT) is an uncommon neoplasm of mesenchymal origin, which can be benign or malignant. Most SFTs develop from the pleura, but they can also be found in other sites. There are only few reports of SFT occurring in the breast. We herein report such a rare case. Sonography demonstrated an ovoid lesion mimicking a fibroadenoma, whereas color Doppler imaging showed marked internal vascularity. A brief literature review on imaging features of SFTs is added. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound, 2016...
