Summary
Proper breast positioning is crucial for mammogram quality. This study found positioning errors in 2.879% of mammograms, impacting diagnostic accuracy and increasing inconclusive examinations.
Area of Science:
- Radiology
- Medical Imaging
- Breast Health
Background:
- Breast positioning is a critical determinant of mammogram quality.
- Correct positioning maximizes imaged breast tissue, minimizes artifacts, and enhances mammogram sensitivity.
Purpose of the Study:
- To retrospectively assess the correctness and incorrectness of breast positioning in mammography.
- Identify common positioning errors to improve mammogram quality and diagnostic accuracy.
Main Methods:
- Retrospective analysis of 1369 female patients undergoing digital mammography.
- Evaluation of Craniocaudal (CC) and Mediolateral Oblique (MLO) views.
- Assessment of positioning errors based on nipple visualization, pectoralis major, pectoral-nipple distance (PND), inframammary fold, and breast quadrant coverage.
Main Results:
- Positioning errors were identified in 2.879% of all mammograms.
- Improper nipple positioning (3.827% in CC view) was the most frequent error.
- Other common errors included inadequate pectoralis major visualization, incorrect inframammary fold depiction, and PND mismatch.
Conclusions:
- Breast positioning is paramount for achieving high-quality mammograms.
- Improper positioning leads to inconclusive examinations and reduced mammographic sensitivity.
- Adherence to proper positioning techniques is essential for accurate breast cancer screening.

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

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...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
