Q

Testicular/Scrotal lesions : what scan is just as good as Acquired DWI

A

Computed DWI & at higher B-values it can enhance the contrast ( so you get more info with the same amount of time)

Q

Predictors functional recover in Acute Ischaemic Stroke

A

mCTA score, HTN and neutrophil count

20
Q

Non-invasive way to assess Pancreatic fibrosis

A

CT
IWR-PPP EP , IWR - PVP , fEVC

20
Q

Left gential vein anatomy

A

anterior to l external iliac vein, ascends between the inferior mesenteric vein and the ureter, and ultimately drains into the left renal vein.

20
Q

Predictor in hospital heart failure post STEMi (not LVEF)

A

Global Radial Strain

21
Q

Sandwich sigh (groin)

A

Ultrasound imaging the left genital vein crosses the iliac vein. consisting of the genital vein, iliac artery, and iliac vein

22
Q

Is the genital vein a single vein

A

no. it may be 2 or three so therefore it is technically a plexus

23
Q

anterior nutcracker phenomenon

A

the left renal vein is compressed between the aorta and the superior mesenteric artery

24
Q

How can radiology save the planet

A

automated turning off of workstations (40-90% of wasted energy in radiology comes from this)

25
Q

NHS responsible for what % of total emissions

A

4%

26
Q

Excision of impalpable breast lesions

A

Hologic LOCalizer- you use a tag instead of a wire

27
Q

Risk factors that increase chance of having abnormal brain scan when PC is dizziness

A

hearing loss, age >65, nystagmus

28
Q

Cystic lung cancer prognosis

A

worse than ground glass

29
Q

Cystic lung cancer location and diganosis

A

Peripheral, difficult to diagnose by bronchoscope

30
Q

How much is a Cyctic lung cancer worth

A

none valuable lesions in the current RECIST (The Response Evaluation Criteria in Solid Tumors)

31
Q

Recurrent AF

A

Larger right atrial appendage

32
Q

Recurrent Persistent AF (as compared to Paroxysmal

A

Larger RA volume

33
Q

Access for Tx of HCC

A

Transradial - better &ptx favourite
not transfemoral

34
Q

Saturday night palsy imaging

A

thickening and a loss of its typical fascicular pattern without any discontinuity. This thickening is most pronounced in the region of the Spinal groove, where the nerve is compressed against the bone

35
Q

Mai cause of radial nerve injury in upper arm

A

Trauma - most commonly humeral bone fractures

36
Q

Radial nerve injury (3)

A

Mild Injury (Neuropraxia): This involves a stretch injury to the nerve.
Moderate Injury (Axonotmesis): This entails partial or complete discontinuity of the axons. Severe Injury (Neurotmesis):
This involves partial or complete discontinuity of the nerve itself.

37
Q

Stump neuroma

A

Lacerate radial nerve

38
Q

Peripheral nerve sheath tumour

A

abnormal fascicular continuity with the mass lesion, a feature that is not typically seen with extrinsic lesions

39
Q

Other things causing radial nerve injury

A

lymphoma
Amyloidosis
locoregional neoplastic or non neoplastic lesions e.g. soft tissue sarcoma, lipomas
Ganglion cyssts
Vascular stuff - aneurysms
Fibromatosis
Bone tumours

40
Q

Other things ptx might do causing radial nerve injury

A

improper use of axillary crutches

41
Q

Other things we might do causing radial nerve injury

A

prolonged use of upper arm tourniquets, lateral
posterior intramuscular injections into the arm, and scar following surgery in the posterior arm

42
Q

Ptx from TB area with TB osteomyelitis/nearby lymphadenitis has Radial nerve neuropathy

A

Maybe its because of the TB

43
Q

Unusual infection causing radial nerve injury

A

HSV

44
Q

Radial nerve entrapment or chronic RN pain not responding to treatment

A

Hydrodissection done under US (usually saline, sometime steroids)
