A rare case of persistent hypoglossal artery associated with contralateral proximal subclavian stenosis.

The persistent hypoglossal artery is rare vascular anomalies. We report the case of a 50-year old man with right hypoglossal artery, ipsilateral hypoplasic internal carotid artery, associated with left proximal subclavian stenosis with subclavian steal syndrome. Power-Doppler-Ultra-Sonography spectral images obtained after the patient exercised the left arm showed mid-systolic deceleration with retrograde late-systolic velocities.

Conventional ultrasound integrated with elastosonography and B-flow imaging in the diagnosis of thyroid nodular lesions.

The purpose of this study was to evaluate the sonographic features of thyroid nodules suspicious for malignancy with standard examination in B-mode and Color Doppler associated with modern techniques such as ultrasound RTE (Real Time Elastosonography) and BFI (B-flow imaging) in correlation with the results of the sonographically guided fine-needle aspiration to establish their role in predicting the risk of malignancy. Between November 2012 and January 2014, 354 consecutive patients (age range, 18-73 years; mean age ± SD, 41.2 ± 9.

How the preoperative ultrasound examination and BFI of the cervical lymph nodes modify the therapeutic treatment in patients with papillary thyroid cancer.

Background: Ultrasound is considered the best diagnostic method for the detection of metastatic cervical lymph nodes (LNs) in patients with papillary thyroid carcinoma (PTC). According to current guidelines, all patients undergoing thyroidectomy for malignancy should undergo preoperative neck ultrasound of the thyroid and central and lateral neck LNs, followed by fine needle aspiration of suspicious LNs. Cervical LN involvement determenes the extent of surgery.

US detection of renal and ureteral calculi in patients with suspected renal colic.

Purpose: The purpose of this study was to determine whether the color Doppler twinkling sign could be considered as an additional diagnostic feature of small renal lithiasis (_5mm).

Methods: 181 patients underwent CT scans performed for other pathologies; the images were also analyzed by a radiologists to identify the incidental presence of renal lithiasis equal to or smaller than 5 mm.These patients underwent an abdominal ultrasound examination, including grayscale analysis of the kidneys and color Doppler.

B-flow twinkling sign in preoperative evaluation of cervical lymph nodes in patients with papillary thyroid carcinoma.

Papillary thyroid cancer (PTC) is the most common histologic type of differentiated thyroid cancer. The first site of metastasis is the cervical lymph nodes (LNs). The ultrasonography (US) is the best diagnostic method for the detection of cervical metastatic LNs.

Multidetector row computed tomography with multiplanar and 3D images in the evaluation of posttreatment mandibular fractures.

Multidetector row computed tomography with multiplanar (MPR) and 3-dimensional (3D) computed tomographic reconstructions is the method of choice in condylar fractures and in the presence of complications for all types of mandibular fracture. MPR and 3D images are the best diagnostic tools to evaluate mandibular fractures after surgical treatment, both after surgery and during follow-up. The conventional radiography is imprecise in the condylar region due to the complicated anatomical bone structures in the area, the lack of sharpness, and image distortion.

A new marker for diagnosis of thyroid papillary cancer: B-flow twinkling sign.

Objective: The purpose of this study was to correlate the presence and patterns of distribution of B-flow imaging (BFI) twinkling signs within thyroid nodules with the histologic evidence of microcalcifications and the results of the sonographically guided fine-needle aspiration to establish their role in predicting the risk of malignancy.

Methods: Between September 2006 and December 2007, 343 consecutive patients with 479 suspected nodules (maximum diameter > 9 mm) were enrolled in this prospective study. Sonographic and BFI examinations were performed with a commercially available real-time sonography system, and all patients also underwent a cytologic evaluation.

Thyroid B-flow twinkling sign: a new feature of papillary cancer.

Background: Microcalcifications (aggregated with psammoma bodies), detected by ultrasound (US), are the most specific feature of papillary thyroid cancer (PTC). Using B-flow imaging (BFI), we identified a new sign (the twinkling sign; BFI-TS) in 'suspect' PTC nodules, which appeared to be generated by microcalcifications.

Objective: To evaluate whether the BFI-TS was predictive of malignancy, we correlated the BFI-TS with the results of fine needle aspiration cytology and histology.
