A Coregistered Ultrasound and Photoacoustic Imaging Protocol for the Transvaginal Imaging of Ovarian Lesions
Published on: March 3, 2023
[Endorectal sonography in rectal carcinoma].
Summary
Endorectal ultrasound accurately assessed rectal cancer infiltration depth in a prospective trial. This imaging technique shows promise for pre-treatment staging, especially when clinical staging is insufficient.
Area of Science:
- Oncology
- Medical Imaging
- Gastroenterology
Context:
- Rectal cancer staging is crucial for treatment planning.
- Clinical staging (digital examination) has limitations in assessing tumor depth.
- A prospective trial was conducted between 1983 and 1985.
Purpose:
- To evaluate the accuracy of endorectal ultrasound in determining rectal cancer infiltration depth.
- To compare endorectal ultrasound findings with pathological examination of excised specimens.
- To assess the utility of endorectal ultrasound in pre-therapeutic staging.
Summary:
- Forty-two patients with rectal cancer underwent endorectal ultrasound for tumor infiltration assessment.
- Endorectal ultrasound demonstrated a 14.2% inaccuracy rate, with no underestimation of infiltration depth.
- The study discusses techniques and interpretation criteria for endorectal ultrasound in rectal cancer.
Impact:
- Endorectal ultrasound offers a promising tool for pre-treatment staging of rectal cancer.
- Improved staging accuracy can lead to more tailored and effective treatment strategies.
- This study highlights the value of advanced imaging in oncological diagnostics.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
