Study Notes
Pelvis and Abdominal Cavity
- Pelvic Regions:
- Greater pelvis (pelvis major) is superior to the pelvic inlet.
- Lesser pelvis (pelvis minor) lies inferior to the pelvic inlet.
Abdominal Quadrants
- The abdominopelvic cavity is divided into four quadrants:
- Right upper quadrant (RUQ)
- Left upper quadrant (LUQ)
- Right lower quadrant (RLQ)
- Left lower quadrant (LLQ)
- Quadrant determination is based on midsagittal and transverse planes crossing at the umbilicus.
Abdominal Regions
- The abdomen can also be divided into nine regions using two vertical and two horizontal lines.
- Surface landmarks assist in defining these regions.
Surface Landmarks
- Vertical lines pass through the mid-inguinal point, located halfway along the inguinal ligament between the pubic symphysis and anterior superior iliac spine.
- Subcostal plane: Connects the lowest points of the costal margins.
- Intertubercular plane: Connects tubercles on the iliac crests.
- Transpyloric plane: Passes through the pylorus, duodenal junction, neck of the pancreas, and hilum of kidneys.
Directional Terminology
- Anterior: Closer to the front.
- Posterior: Closer to the back.
- Superior: Higher or towards the head.
- Inferior: Lower or towards the feet.
- Medial: Closer to the midline.
- Lateral: Further from the midline.
- Longitudinal: Related to length.
- Superficial: Close to the body surface.
- Deep: Further from the body surface.
Body Planes
- Transverse (Axial): Divides the body into upper and lower portions.
- Sagittal: Divides the body into right and left sides; midsagittal specifically divides into equal halves.
- Coronal: Divides the body into anterior (front) and posterior (back) sections.
- Longitudinal: Represents the longest length of an organ.
Sonographic Terminology
- Anechoic/Sonolucent: Echo-free appearance (black).
- Echogenic: Structures that produce echoes (bright).
- Hypoechoic: Less bright than another area.
- Hyperechoic: Brighter than another area.
Organ Characteristics
- Echo texture: Describes appearance of soft tissue structures as homogeneous or heterogeneous.
- Parenchyma: Homogeneous texture; liver is moderately echogenic, while kidneys are hypoechoic compared to the liver.
Imaging Standards
- Ultrasound documentation requires specifying the scanned organ, the scanning plane, and patient position.
- Accurate anatomical landmarks and probe orientation are crucial for proper identification.
- Knowledge of gross and sectional anatomy, anatomical variations, and sonographic appearances is essential.
Anatomical Position
- The standard position assumes the body is upright, head facing forward, arms at the sides, with palms and toes directed forward.
Body Cavities
- Dorsal Cavity: Posterior side; includes cranial and spinal cavities.
- Ventral Cavity: Anterior side; divided into thoracic and abdominal cavities by the diaphragm.
- Thoracic Cavity: Enclosed in the rib cage; houses the bronchi and lungs.
- Abdominal Cavity: Extends from the diaphragm down and connects with the pelvic cavity.
- Pelvic Cavity: Extends from the iliac crests down to the pelvic diaphragm; continuous with the abdominal cavity.
- False Pelvis: Positioned superior to the pelvic inlet.
