Summary
This guideline details best practices for breast ultrasound, covering diagnostic, screening, and interventional uses. It emphasizes multimodality correlation and integration into breast imaging for optimal patient care.
Area of Science:
- Radiology
- Medical Imaging
- Breast Health
Background:
- The Canadian Association of Radiologists (CAR) Practice Guidelines on Breast Imaging and Intervention are essential for standardized care.
- Part III specifically addresses the critical role of breast ultrasound in modern practice.
Purpose of the Study:
- To provide comprehensive recommendations for the use of breast ultrasound.
- To outline standards for diagnostic, supplemental screening, and interventional applications.
- To ensure consistent and high-quality breast ultrasound services.
Main Methods:
- Consensus-based development of recommendations.
- Review of current clinical indications, equipment, and technical performance standards.
- Inclusion of axillary assessment, documentation, and structured reporting (BI-RADS®).
Main Results:
- Detailed guidance on handheld and automated whole-breast ultrasound techniques.
- Emphasis on quality assurance and personnel qualifications.
- Recommendations for multimodality correlation and timely diagnostic assessment.
Conclusions:
- Breast ultrasound is a vital tool in contemporary breast imaging.
- Integration with other imaging modalities and adherence to guidelines improve patient outcomes.
- Radiologists retain final responsibility for interpretation and management decisions.

01:20Ultrasound I: Abdominal Ultrasonography
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

01:24Imaging Studies II: Ultrasonography
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
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.

01:30Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
