Diagnostic radiology: women imaging Flashcards
What are the 2 basic views of mammography?
Craniocaudal (CC)
Mediolateral oblique (MLO)
What is the indication of breast US elastography?
What is the use of breast MRI?
- High risk screening
- Patient with breast augmentation
- Detect occult cancer and evaluate disease extent
What features are observed for in mammogram for malignancy?
Tumour (mass, density)
- poorly circumscribed, irregular, spiculated, dense
Microcalcification
- irregular, pleomorphic sizes and density, linear,
clustered Retraction (distortion)
What are USG findings of breast malignancy?
- Hypoechoic
- Irregular mass
- Vascularity
What are USG findings of breast mass (benign)?
- Round or oval
- No vascularity
- Anechoic (breast cyst)
- Hypoechoic (fibroadenoma)
Benefits and disadv of transvaginal/transabd ultrasound?
For pelvic pain what is first line imaging and other possible imagings done?
US: initial imaging investigation
MRI: useful in identifying gyne causes e.g. endometriosis, adenomyosis
CT: for non gynaecological cause
What imaging for pre-menopausal abnormal vaginal bleeding?
- US: imaging of choice to exclude the presence of leiomyoma (fibroid), endometrial or adnexal abnormality
- If bleeding persists, gynaecological referral for hysteroscopic examination should be considered
What imaging for post-menopausal abnormal vaginal bleeding?
- TVUS: recommended to assess endometrial thickness
- Endometrial thickening ≥5 mm or abnormal morphology should be investigated by biopsy
What is sequence of imaging for suspected pelvic mass?
- US: recommended as initial evaluation to confirm the presence of pelvic mass and likely origin.
- MRI: indeterminate pelvic mass on US and for further characterisation.
- CT: reserved for staging pelvic mass with high probability of malignancy (skip MRI if there is ascites and other suggestive signs).
