Diagnosis of thyroid space-occupying lesions using real-time contrast-enhanced ultrasonography with sulphur hexafluoride microbubbles / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To explore the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of thyroid occupied lesions with injection of sulphur hexafluoride microbubbles.</p><p><b>METHODS</b>Fifty nine cases of conventional ultrasonic diagnosis of thyroid lesions in patients with 73 lesions re-sulfur hexafluoride microbubble ultrasound contrast real-time inspection, the use of CEUS and contrast pulse sequencing (CPS).</p><p><b>RESULTS</b>Seventy-three lesions were satisfied with the dynamic contrast perfusion imaging. Ultrasound contrast prompted the 15 lesions (13 cases) of malignant lesions by postoperative pathology confirmed papillary thyroid carcinoma, ultrasound images showed a low or mixed echo, boundary ambiguity, accompanied by Microcalcification foci, blood flow distribution I rank or grade III. Ultrasound prompted 58 lesions (46 cases) of benign lesions, blood flow distribution of grade II or III, the performance of a variety of two-dimensional ultrasound image, showing cystic, solid or liquid-solid mass, border clearance. Contrast with the surrounding thyroid tissue, lesions<or=20 mm in diameter papillary thyroid carcinoma are poor blood supply type; diameter>or=20 mm papillary thyroid carcinoma, manifested prior to the beginning of the adjacent thyroid substance to enhance and dissection, showing the form of high-enhanced perfusion; thyroid follicular adenoma as early as the beginning of the adjacent thyroid substance to enhance and dissection, mass retained within the contrast agent longer time, showing the form of high-enhanced perfusion; nodular goiter enhanced for thyroid nodules and adjacent synchronization started to pick up in real terms, after the 6 lesions showed nodular contrast slightly earlier than the adjacent thyroid substance started to pick up, 28 lesions with synchronous real beginning of the adjacent thyroid dissection, 11 lesions of nodular dissipated early on (started receding time < or = 25 s) adjacent to thyroid substance.</p><p><b>CONCLUSION</b>The real-time CEUS with injecting sulphur hexafluoride microbubbles is valuable in the diagnosis and differential diagnosis of the thyroid occupied lesions.</p>

Features of contrast-enhanced ultrasound imaging in malignant lymphoma after treatment with integrated Chinese and Western medicine / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To investigate the typical features of contrast-enhanced ultrasound imaging in malignant lymphoma after treatment with integrated Chinese and Western medicine.</p><p><b>METHODS</b>Ten patients with malignant lymphoma after different treatment cycles were examined with contrast-enhanced sonography, including 21 lymphnodes (in the neck, space of iliac blood vessels, retroperitoneum) and 7 spleen infiltrations.</p><p><b>RESULTS</b>The blood flow pattern distribution in lymph node before freatment was significantly different from that after trentment showed either by color Doppler flow imaging (CDFI) or by contrast-enhanced ultrasound (CEUS, P < 0.05), and the difference in splenic lesion was shown by CEUS (P < 0.05).</p><p><b>CONCLUSION</b>Contrast-enhanced ultrasound imaging is a valuable tool for the follow-ups of malignant lymphoma after chemotherapy and guiding subsequent treatment.</p>

Progress of ultrasonography in diagnosis of breast tumors / 肿瘤研究与临床

The incidence of breast tumors has increasing trend year by year recently.Ultrasound has become a main means of screening and diagnosis in breast tumors for its lack of radiation,harmlessness to op- erator and patient,convenience and repeatrbility.Grey-scale uhrasonography,color doppler flow imaging,col- or doppler energy contrast enhanced ultrasonogrphy,3-D ultrasonography,elastomography,ultrasound-guided biopsy are main methods for both detection and differentiation in breast tumors.The purpose of this paper is to review the applications of these techniques in breast tumors diagnosis.
