Med Conditions: Radiography

Wilhelm Conrad Roentgen

who discovered x-radiation on november 8, 1895?

nobel prize in 1901

what was Wilhelm Conrad Roentgen awarded for his findings?

his wife

who was Wilhelm Conrad Roentgen's test subject?

from cancer

how did Wilhelm Conrad Roentgen and his wife die?

may 1896

when was fluroscope developed?

floroscope

What allows medical professionals to view small anatomical structures when placed in front of the x-ray tube?

Anna Bertha's left hand (because it contained removable artifacts)

what is the most famous x-ray?

a bundle of energy

travels at speed of light

cannot be focused

can ionize atoms

what is an x-ray?

radiologic sciences

what is the profession using computers and technology to view inside of the human body? can be diagnostic, therapeutic, or both; may study anatomy or physiology

radiographer

what profession positions the patient, sets techniques (mAs and kVp), and ensures radiographic quality of finished radiograph

radiologist

what profession reviews radiographs, dictates report of findings, and usually has less patient contact

As low as reasonably achievable (ALARA)

what is part of the philosophy to keep the radiographer safe to do their job to decrease time, increase distance, and increase shielding

HIPAA (Health Insurance Portability and Accountability Act)

what is part of the philosophy to protect patient autonomy, patient privacy, respect, and empathy

2 views are better than one

when taking images, what is part of the philosophy when determining how many pictures to take

variety (children to adults)

what type of patients do radiographers see?

static image

what kind of image has no motion and may be acquired with stationary or portable equipment

dynamic images

what type of imagines are also known as floroscopy and take a series of static images. these may be viewed in "cine" mode (images in motion). This is often used to examine function

c-arm

what machine is a mobile floroscopy?

sonography

- aka ultrasound

- uses sound waves and doppler effect

- no ioning radiation

mammography

- used for diagnosis and prevention

- utilizes low dose of ionizing radiation

- need high detail in images

CT (computed tomography)

- uses x-rays rotating around pt

- only acquires axial images

- computer reconstructs data to create coronal and sagittal images and 2-D and 3-D images

MRI (magnetic resonance imaging)

- excellent for imaging soft tissue

- uses strong magnets and radiofrequencies

- image reconstruction via computer

nuclear medicine

- uses radiopharmaceuticals (i.e. flurodeoxyglucose) and special cameras

- measure radiation emitted from patient

- useful when examining functions of an organ

- may also be used for ablation (i.e. thyroid)

radiation therapy

- utilizes high doses of radiation

- targets cancer cells, while sparing healthy cells

- medical dosimetrist - creates and mages radiation treatment plans
