Further progress in intraluminal sonography has led to the development of a 6 French ultrasound imaging catheter. This report demonstrates in vivo results using this new technique in a swine. Intraluminal echographic images obtained from the aorta and iliac arteries were of good quality. Artifacts such as image distortion were related to the 20 Mhz mechanically rotating tip motion and caused a loss of image quality. Atherosclerotic lesions could be visualized. The characteristics of the echo image of an atherosclerotic lesion related to the composition of corresponding histological sections of the lesion. Intraluminal sonography may develop into a new diagnostic tool, further enhancing progress in atherosclerosis research and improving the evaluation of coronary arteries and perivascular structures. Combined use with balloon angioplasty might also improve invasive therapeutic procedures.

Background: Fistula-in-ano is an abnormal tunnel formation linking the anal canal with the perineum and perianal skin. Multiple imagining methods are available to evaluate it, among which magnetic resonance imaging (MRI) is the most advanced noninvasive preoperative method. However, it is limited in its visualization function.

Article Synopsis
- Acute appendicitis and acute cholecystitis often occur together, and surgical management is effective for both conditions when they present simultaneously.
- A 30-year-old female patient presented with abdominal pain and underwent imaging that confirmed the diagnoses, leading to a successful surgical intervention combining cholecystectomy and appendectomy.
- The case underscores the importance of recognizing the possibility of both conditions occurring together and utilizing established management guidelines for effective treatment.
Use of radial endobronchial ultrasonography in the distinction between intraluminal and mixed type tracheal schwannoma: A case report.

Tracheal schwannomas are exceedingly rare, accounting for a minute fraction of primary tracheal tumors. They are classified into intraluminal and mixed types, with treatment strategies varying significantly between these subtypes. While thorax tomography is usually sufficient to distinguish intraluminal and mixed type, endobronchial ultrasonography (EBUS) can also be used in cases where the distinction cannot be made clearly with tomography.

In dogs, the characterization of intraluminal uterine contents has been subjectively carried out by the operators. The aims of this study were: 1) To ultrasonographically describe and compare the echogenicity and heterogeneity of the intraluminal uterine contents in bitches using digital analysis; 2) To assess the cytology of the uterine contents; 3) To evaluate the effect of clinical, ultrasonographic, bacteriological and cytological parameters on intraluminal contents echogenicity and heterogeneity. Twenty-one intact, 3-24 kg, 1-12 years of age, female dogs with ultrasonographically detected uterine content were included.

Background: Small intestinal obstruction (SIO) is a blockage of the intestinal lumen by blunt foreign bodies, neoplasms originating from the intestinal wall or thick chyme. This study analysed the medical records (only data) of 110 cattle with SIO and described the clinical findings, treatment and outcome. These findings were compared between surviving and non-surviving cattle, and among the affected regions such as the duodenum, jejunum and ileum.
