Objective: To discuss the diagnostic value of multislice spiral tomography (CT) combined with CT angiography (CTA) technology in intra-abdominal undescended testis secondary seminoma cases.
Methods: We retrospectively analyzed the CT and CTA imaging features of CT and CTA findings of nine patients with an intra-abdominal undescended testis secondary seminoma.
Results: The tumors in all nine patients were mainly solid, and the average CT value was 38.
Article Synopsis
- Gadobenate dimeglumine showed superior diagnostic performance compared to gadopentetate dimeglumine in Breast MRI screening, with pooled sensitivities of 0.99 and 0.93, respectively.
- The specificity values for gadobenate and gadopentetate were also higher at 0.924, compared to 0.838, indicating that gadobenate is more reliable at confirming negative results.
- The study analyzed 17 research articles with a total of 1934 patients and concluded that gadobenate dimeglumine is a more effective contrast agent for breast cancer screening, offering clinically relevant differences in diagnostic performance.
Purpose: To investigate the presentation of splenic hamartomas (SHs) on ultrasonography (US), CT and MRI.
Methods: Nine patients (5 males and 4 females, mean age, 52.8 years) with pathologically proven SHs were included in this study.
Background: Colloid carcinomas of the pancreas have better prognosis than ordinary ductal adenocarcinoma, and preoperative distinction of colloid carcinoma from other pancreatic tumors is valuable for patient therapeutic planning and prognosis assessment. However, data about CT features of colloid carcinoma are very limited. This study aimed to investigate the CT features of this tumor.

To overcome these obstacles, a new multifunctional drug delivery system is developed, which is based on covalently attaching genistein onto Fe3O4 nanoparticles coated by cross-linked carboxymethylated chitosan (CMCH). The structure of the Fe3O4-CMCH-genistein nano-conjugate was confirmed by transmission electron micrographs (TEM), X-ray diffraction (XRD) and Fourier-transfer infrared (FT-IR) spectroscopy.

Conclusion: The imaging feature of patients exposed to food contaminated with melamine and cyanuric acid was multiple calculi of the urinary tract that varied greatly in size and shape. Most patients presented with symptoms of urinary obstruction.
Aim: To explore the feasibility of computed tomography (CT)-guided percutaneous ethanol injection (PEI) using a disposable curved needle for treatment of malignant liver neoplasms and their metastases in retroperitoneal lymph nodes.
Methods: CT-guided PEI was conducted using a disposable curved needle in 26 malignant liver tumors smaller than 5 cm in diameter and 5 lymph node metastases of liver cancer in the retroperitoneal space. The disposable curved needle was composed of a straight trocar (21G) and stylet, a disposable curved tip (25 G) and a fine stylet.
