Duplex ultrasonography
- Combination of two transducers to see blood vessesl both in superficial and deep locations
- Simultaneous doppler analysis of bilateral limbs by two sonographs
- 2D US examination, then doppler analysis by ”pencil” probe
- Simultaneous 2D US with doppler sampling from the vessels specified on the 2D image
- Simultaneous 2D US with doppler sampling from the vessels specified on the 2D image
Duplex ultrasonography is used in vascular studies; refers to the simultaneous use of both grayscale or color Doppler to visualize the structure of, and flow within, a vessel and sprectral (waveform) doppler to quantitate flow.
For what does a radiologist look for when performing a FAST-exam?
- Free abdominal fluid
- Gall bladder inflammation
- Kidney stones
- Cysts
a. Free abdominal fluid
FAST is a rapid bedside US examination performed by surgeons, emergency physicians and certain paramedics as a screening test for blood around the heart or abdominal organs after trauma.
What is the first modality choice in symptomatic bone tumors?
- PET-CT
- Scintigraphy
- Conventional x-ray
- CT
c. Conventional x-ray
US sign of intussuception:
- ”target” sign
- ”whirlpool” sign
- ”psudokidney”
- ”comet” sign
a. ”target” sign
the target sign of intestinal intussusception, also known as the doughnut sign, or bulls eye sign. The appearance is generated by concentric alternating echogenic and hypoechogenic bands. The echogenic bancs are formed by mucosa and muscularis, whereas submucosal is responsible for the hypoechogenic bands.
MR spectroscopy is a useful method in diagnosis of
- Renal cell cancer
- Ovarian cancer
- Testicular cancer
- Prostate cancer
d. Prostate cancer
MRS is currently used to investigate a number of diseases in the human body, most notably cancer (brain, breast and prostate), epilepsy, alzheimers, parkinsons and huntingtons. MRS has been used to diagnose pituitary tuberculosis. Prostate cancer: combined with MRI and given equal results, then the #D MRS can predict the prevalence of a malignant degeneration if prostate tissue by approx. 90%. The combination of both metods may be helpful in the planning of biopsies and therapies of the prostate, as well as to monitor the success of a therapy.
Choose the correct statement regarding hyperacute cerebral infarcts
- Hyperdense media sign is always visible
- Hyperdense media sign is visible in 25-50% of the cases
- Hyperdense media sign is never visible
- Hyperdense media sign is visible in 10-15% of the cases
b. Hyperdense media sign is visible in 25-50% of the cases
What is the diagnostic strategy in extracranial carotid disease?
- Primary examination is DSA which is complemented by CTA or MRA, US is only for kids
- Primary examination is duplex US for screening and follow-up: probless solving advanced imaging for selected cases is CTA or MRA – catheter angiography (DSA) is mainly for therapeutic interventions
- US-guided puncture of the CCA and then directed angiography of the affected side
- Primary examination is CTA; MRA is only for iodine-sensitive patients; DSA for all patients preceding surgery and duplex US for post-surgical complications
b. Primary examination is duplex US for screening and follow-up: probless solving advanced imaging for selected cases is CTA or MRA – catheter angiography (DSA) is mainly for therapeutic interventions
- Carotid artery stenosis is usually diagnosed by color flow duplex US scan of the carotid arteries in the neck. This involves no radiation, no needles, and no contrast agents that may cause allergic reactions. This test has good sensitivity and specificity.
- CTA or MRA may be useful. With contrast: contraindicated in patients with renal insuffieicency, catheter angiography has a 0.5-1% risk of stroke, MI arterial injury or retroperitoneal bleeding. The investigation chosen will depend on the clinical question and the imaging expertice, experience and equipment available.
