Enwk5- 2-9 Ricci Bone Densitometry/ Pituitary And Adrenal Imaging

Front 1

Bone densitometry (bone mineral density machine)

Back 1

density and mass of women to prevent osteoporosis

Front 2

Of the bone density exams which is most commonly used?
Other uses?

Back 2

dual x-ray absorptiometry...
- 2 energy levels created by filter or generator, low radiation

- can look at develop of bone where there has been fracture or even a mass on a bone

Front 3

What is the T score in bone densitometry and what are the 3 measures?

Back 3

standard deviation of young adult
- Normal >(-1.0)
- Osteopenia (loss of bone density (-1.0)- (-2.5)
- Osteoporosis (loss of bone mass) <(-2.5)

Front 4

Normal bone density read out shows?

Back 4

BMD- (bone mineral density), %, t-score for young adult and for age matched

Front 5

If you find bone density is extremely elevated... what do u need to look for and where?

If the bone density is super low what may cause it?

Back 5

often in the lumbar spine may see osteophytes, and diffuse region of sclerosis

- lesion from met etc.

Front 6

Pituitary need what type of imaging? VIEW?
If you are looking for microadenoma what is important imaging?

Back 6

MRI sagittal and coronal

- timed intervals in the coronal plain "dynamic imaging" after dye has been given, see changes after contrast has been given

Front 7

What is empty sella and what clinical significance?

Back 7

defect in sella diaphragm allows CSF extension into the sella
- usually asymptomatic

Front 8

Massive hemorrhage into pituitary adenoma causing infarction and necrosis
presents how?

Back 8

Sheehan syndrome
severe headache, sudden vision loss

Front 9

Color of fluid and ventricular system in T1?

What lights up in T1

Back 9

black

- fat and blood are bright in T1

Front 10

Adrenal imaging usual first step?

When is U/S good to image the adrenal gland?

Back 10

CT


U/S good for the infants

Front 11

If you think there is adenoma and it enchances with dye what should you think?

Back 11

adenomas should not enhance so think something else
- MRI can tell if you have a lot of fat

Front 12

When would you use angiography/venography for adrenal gland

Back 12

adrenal gland sampling to see hormones produced in the blood

Front 13

Bilateral calcifications in adrenal regions should think?

Back 13

prior hemorrhage caused calcifications

Front 14

Malignant masses on adrenal glands often show? Where do mets often come from

Back 14

could be bilateral but show more dense than fat would (lighter on CT)

- mets often come from lungs
