what dedicated mammography unit is used for ?
for breast imaging
It’s equipped with specialized compression paddles and X-ray tubes
patient preparation ?
Explanation and consent ( inform consent)
Clothing and jewelry
Patient history ( Biopsies)
Is positioning of the patient is important ?
yes it is crucial for obtaining accurate images such as craniocaudal (CC) and
mediolateral oblique (MLO
What are CC and MLO ?
craniocaudal is top bottom
Mediolateral is side view of breast taken
Why compression is important in mammography ?
to spread out breast tissue and reduce the thickness, which helps to obtain clearer images
Exposure factors of mammography ?
kVp : is 25-28
Time : short to avoid patient motion
mA : 20-100
SID : 20-30
Image receptors of mammography ?
Single side film
Computed radiography ( contains a phosphor)
Direct digital mammography
Detector contains
( thallium-activated CsI phosphors)
Special Considerations ?
Breast implants ( like silicone gel filled )
which they make it hard to see image clearly
Dense Breast tissues ( which can make interpretation challenging )
Types of Dental radiography ?
Intra-oral radiography
Extra-oral Radiography
Panoramic Radiography
CT- Dental radiography
It is portable , units with an adjustable arm to allow for in chair is ?
Intra oral which has 60 kvp
face to skin ( 200mm)
Image receptors like film and
Digital like CR and DR
types of film radiographs ?
Periapical , bite wing and occlusal
What is used to evaluate the relationship between anatomical points at the teeth, jaws and skull bones ?
Lateral Cephalometric radiography
Extra oral
