Thyroid nodules are very common all over the world, and China is no exception. Ultrasound plays an important role in determining the risk stratification of thyroid nodules, which is critical for clinical management of thyroid nodules. For the past few years, many versions of TIRADS (Thyroid Imaging Reporting and Data System) have been put forward by several institutions with the aim to identify whether nodules require fine-needle biopsy or ultrasound follow-up.

August 2013
Background: It is a globally challenging problem to differentially diagnose biliary atresia (BA) from other disease processes causing infantile cholestatic jaundice. The high-frequency ultrasonography (HUS) yields much improved spatial resolution and therefore, might show better image in BA diagnostic examination. The present study was to evaluate the HUS on the diagnosis of BA in infants with jaundice.

- The study aimed to evaluate the effectiveness of color Doppler ultrasonography (CDUS) and nocturnal electrobioimpedance volumetric assessment (NEVA) in diagnosing erectile dysfunction (ED) and its causes.
- Conducted on 45 ED patients, the research classified participants based on CDUS results and compared NEVA parameters across different ED groups, revealing that most non-vasculogenic ED patients maintained normal nocturnal penile tumescence (NPT).
- The findings showed that NEVA results correlated well with CDUS data, suggesting NEVA has potential in identifying the causes of ED, despite only one significant difference observed between specific ED groups.
The value of color Doppler ultrasonography in monitoring normal orthotopic liver transplantation and postoperative complications.
Hepatobiliary Pancreat Dis Int
February 2003
Objective: To assess the value of color Doppler ultrasonography in monitoring normal orthotopic liver transplantation and postoperative complications.
Methods: Forty-one patients after orthotopic liver transplantation were examined by using color Doppler flow imaging to observe the hepatic blood flow and change of ultrasonography of the hepatic parenchyma and bile duct. The measured indexes included maximum blood flow velocity, time-average blood flow velocity (TAV), resistance index (RI) and diameter of the bile duct.
