what are body cavities?
spaces within the body that help protect, separate, and support internal organs
what is the dorsal cavity lined by?
meninges
what is the cranial cavity formed by and contain?
formed by skull and contains brain
what is the vertebral cavity formed by and contain?
formed by vertebral column and contains spinal cord
what is the pleural cavity lined by?
pleura and peritoneum
what are the 3 ventral cavities?
thoracic, abdominal and pelvic cavities
what is the function of the mediastinum?
divides the thoracic cavity into two pleural cavities
what does the pleural cavity enclose?
the lungs
what does the pericardial cavity surround?
the heart
what does the mediastinum contain?
all the thoracic viscera except the lungs
what is the abdominopelvic cavity divided into?
the superior abdominal and inferior pelvic cavity

stomach, spleen, pancreas, liver, gallbladder, small intestine,most of the large intestine
what does the viscera of the pelvic cavity include?
urinary bladder, portions of the large intestine and internal f + m reproductive structures
what is medical imaging?
Specialised branch of anatomy and physiology essential for the diagnosis of many disorders
what is the function of medical imaging?
to view inside the body to observe whether anatomy is present in order to diagnose disease
what is conventional radiography?
A single burst of x-rays
what kind of image is produced by conventional radiography?
Produces 2-D image on film
Poor resolution of soft tissues
what is the major use of conventional radiography?
use in osteology
give examples of conventional radiography?
Chest x-ray (CXR)
Abdominal x-ray (AXR)
what is Computed Tomography (CT Scan)?
moving x-ray beam
what image is produced by CT scan?
Image produced video monitor of a cross-section through body
what is an advantage of CT scan?
reveals more soft tissue detail
what kind of image is given by CT scan?
Multiple scans used to build 3D views
what is Digital Subtraction Angiography (DSA)?
Radiopaque material injected into blood vessels
what is removed in a DSA?
Distracting structures removed by subtracting pre-contrast image from contrast image
what does a DSA show?
Image of blood vessels is shown on a monitor
what is Ultrasound Scan (USS)?
High-frequency sound waves emitted by hand-held device
what is advantages of USS?
Safe, noninvasive & painless
what is a sonogram displayed on?
video monitor
what is USS used for?
foetal ultrasound and examination of pelvic & abdominal organs, heart and blood flow through blood vessels
what is Magnetic Resonance Imaging (MRI)?
Body exposed to high-energy magnetic field
how does MRI scan work?
Protons align themselves relative to magnetic field
Pulse of radiowaves are used to create a video image
when should MRI not be used?
Do not use on patients with metal in their body
what is an advantage of MRI scan?
Reveals fine detail within soft tissues
what is a Positron Emission Tomography (PET) scan?
Substance that emits positively charged particles is injected
how does a PET scan work?
Collision with -vely charged electrons in tissues releases gamma rays
Camera detects rays & computer generates image displayed on monitor
