Qualitative and Semiquantitative Elastography for the Diagnosis of Intermediate Suspicious Thyroid Nodules Based on the 2015 American Thyroid Association Guidelines.

Objectives: To evaluate qualitative and semiquantitative elastography for the diagnosis of intermediate suspicious thyroid nodules based on the 2015 American Thyroid Association (ATA) guidelines.

Methods: Through a retrospective search of our institutional database, 746 solid thyroid nodules found on grayscale ultrasonography, strain elastography, and ultrasound-guided fine-needle aspiration between June and November 2009 were collected. Among them, 80 nodules from 80 patients with an intermediate suspicion of malignancy based on the 2015 ATA guidelines that were 10 mm or larger were recruited as the final study nodules.

Serial Ultrasound Findings After Laser Ablation for Benign Breast Lesions on Long-Term Follow-Up: Implications for Evaluation of Procedural Success.

Objective: The purpose if this study was to describe the follow-up ultrasound (US) findings of percutaneous US-guided laser ablation for small benign breast lesions, and to define the procedural success.

Background Data: There are limited reports on follow-up imaging after laser ablation, because the ablated tumors were generally resected by surgery.

Materials And Methods: US-guided laser ablation was performed on 19 benign breast lesions in 10 patients.

The effects of QRS duration and pacing sites on the acute hemodynamic changes during right ventricular pacing.

Background: Has been reported that patients exhibiting prolonged paced QRS duration tend to have more serious heart disease, and the paced QRS duration can be an effective indicator of impaired left ventricular function. However, the acute and chronic hemodynamic effects of paced QRS duration and pacing sites during right ventricular (RV) pacing remain unknown.

Methods: A total of 14 patients who underwent electrophysiologic study for paroxysmal supraventricular tachycardia were examined.
