Chapter 13 Flashcards
Imaging: Arteriogram
allows to see vessel
best pictures of blood vessels
Imaging: Arthroscopy
widely used in surgery
Uses a fibre-optic arthroscope to view the inside of a joint
Imaging: Bone Scan
radioactive tracer
Stress fractures can be detected
Imaging: Computed Tomography (CT)
Cross-sectional image of tissues
View injured structure from many angles
Imaging: DEXA Scan
Dual Energy X-Ray absorptiometry
Measure bone mineral density
more flexible than a bone scan
examine spine and extremities
Imaging: Doppler Ultrasonography
Ultrasound to examine blood flow in major arteries and veins in arms and legs
Help diagnose blood clot, venous insufficiency, arterial occlusion, abnormalities in blood flow
Imaging: Echocardiography
Ultrasound to produce a graphic record of internal cardiac structures
Used to visualize cardiac valves and determine dimensions of left atrium and both ventricles
Imaging: Electrocardiography (ECG)
electrical activity of the heart recorded
Determines if heart follows certain pattern
Imaging: Electroencephalography (EEG)
Electrical potentials used in the brain recorded
Imaging: Electromyography
Recording of a muscle contraction with surface or needle electrodes
Imaging: Glucometer
Determine the approximate concentration of glucose in the blood
Normal blood glucose level is less than 100mg/dl when fasting and less than 140mg/dl 2 hours after eating
Imaging: Magnetic Resonance Imaging (MRI)
provides clearer images than CT scans
Currently test of choice for detecting soft-tissue lesions
Imaging: Myelography
Opaque dye put into spinal canal
Detect conditions such as tumours, nerve root compression and disk disease
Imaging: Nerve Conduction Velocity
may provide key info about a number of neuromuscular conditions
Measures speed of which a muscle action occurs
Imaging: Peak Flow Meter
quickly assess a patients peak expiratory flow rate or the ability to quickly expire or breathe air out of the lungs
Most often used in pt who have some type of disease or condition that obstructs airflow through bronchii
Imaging: Plain Film Radiography (X-Ray)
helps identify fractures and dislocations or any bone abnormality
May be used to r/o serious diseases (infection or neoplasm) (Chest XR)
Imaging: Positron Emission Tomography (PET)
Injection of a radioactive tracer chemical to produce a 3D image
Distinguish between loving and dead tissue or benign and malignant tissue
Detect abnormal cellular activity in the very early stages
used in conjunction with MRI and/or CT scans
Imaging: Pulse Oximetry
assessing breathing by indirectly measuring oxygen saturation of arterial blood
Imaging: Refractometer
accurate method of measuring hydration status
Precise reading of specific gravity of urine
Imaging: Ultrasonography (ultrasound)
High-frequency sound waves to produce pictures of anatomical structures
Shows structure and movement of body’s msk structures, organs and blood
Imaging: Urinalysis
pee test
yields a large quantity of information
- kidney ability to concentrate and dilute fluids
- how acid or alkaline urine is
- presence of ketones
- presence of proteins
- presence of nitrate
Organs in Left Lower Quadrant (4)
- part of descending colon
- Sigmoid colon
- Left ovary and tube
- Left ureter
Organs in Left Upper Quadrant (7)
- stomach
- Spleen
- Left lobe of liver
- Body of pancreas
- Left kidney and adrenal gland
- splenic flexure of colon
- part of transverse and descending colon
Organs in Lower Right Quadrant (4)
- cecum
- appendix
- right ovary and tube
- right ureter
Organs in Upper Right Quadrant (7)
- liver
- Gall bladder
- Duodenum
- Head of pancreas
- Right kidney and adrenal gland
- Hepatic flexure or colon
- Part of transverse and ascending colon
