RCR Journal November Flashcards
Reduces risk of extraversion allergic reactions
Contrast media warming to 37degrees
Main contrast that showed lower risk of extraversion reactions when warmed
Iohexol 350
Pros/Cons of AI in Radiology
Patient education materials. Pro more accessible. Cons- sometimes inaccurate
Which AI tools
Chat GPT & Google Gemini
Risk factors for stroke in posterior circulation stroke
Diabetes , HTN, degree of enhancement, plaque length
Risk of stroke in dissection
VBA/BS ratio
Risk factor common to both posterior circulation atherosclerosis and dissection
Arterial remodelling capacity
Posterior circulation IMH-type dissection
Greater potential for positive remodelling
imaging diagnosing dissection
HR-VWI
Higher stroke risk
Atherosclerosis
Testicular/Scrotal lesions : what scan is just as good as Acquired DWI
Computed DWI & at higher B-values it can enhance the contrast ( so you get more info with the same amount of time)
Differentiate between AICH and CCM in CT Head
Histogram Analysis
How to make breast cancer USS better
Add in DL will give better diagnostic efficiency
Improve ZTE lung MRI
DLR. Gives potential to pick up pulmonary parenchymal disease
One stop shop for acute ischameic storke
CT head and neck , 512 slice detector. Logistically better and better images
Automate bone fracture detetcion Xray humerus
Ensemble model (detail you wont need to know MobileNetV2, Vgg16, InceptionV3, and ResNet50, using histogram equalization for preprocessing and a Global Average Pooling layer)
Predicting Malignant MCA infarct in patients with Acute Ischamic stroke
Higher baseline subcortical net water uptake in CT
Imaging biomarkers for Glioma
Intratumoral and periotumoral MRI imaging predicts survival rate
Predictors functional recover in Acute Ischaemic Stroke
mCTA score, HTN and neutrophil count
Non-invasive way to assess Pancreatic fibrosis
CT
IWR-PPP EP , IWR - PVP , fEVC
Left gential vein anatomy
anterior to l external iliac vein, ascends between the inferior mesenteric vein and the ureter, and ultimately drains into the left renal vein.
Predictor in hospital heart failure post STEMi (not LVEF)
Global Radial Strain
Sandwich sigh (groin)
Ultrasound imaging the left genital vein crosses the iliac vein. consisting of the genital vein, iliac artery, and iliac vein
Is the genital vein a single vein
no. it may be 2 or three so therefore it is technically a plexus
anterior nutcracker phenomenon
the left renal vein is compressed between the aorta and the superior mesenteric artery
How can radiology save the planet
automated turning off of workstations (40-90% of wasted energy in radiology comes from this)
NHS responsible for what % of total emissions
4%
Excision of impalpable breast lesions
Hologic LOCalizer- you use a tag instead of a wire
Risk factors that increase chance of having abnormal brain scan when PC is dizziness
hearing loss, age >65, nystagmus
Cystic lung cancer prognosis
worse than ground glass
Cystic lung cancer location and diganosis
Peripheral, difficult to diagnose by bronchoscope
How much is a Cyctic lung cancer worth
none valuable lesions in the current RECIST (The Response Evaluation Criteria in Solid Tumors)
Recurrent AF
Larger right atrial appendage
Recurrent Persistent AF (as compared to Paroxysmal
Larger RA volume
Access for Tx of HCC
Transradial - better &ptx favourite
not transfemoral
Saturday night palsy imaging
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
Mai cause of radial nerve injury in upper arm
Trauma - most commonly humeral bone fractures
Radial nerve injury (3)
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.
Stump neuroma
Lacerate radial nerve
Peripheral nerve sheath tumour
abnormal fascicular continuity with the mass lesion, a feature that is not typically seen with extrinsic lesions
Other things causing radial nerve injury
lymphoma
Amyloidosis
locoregional neoplastic or non neoplastic lesions e.g. soft tissue sarcoma, lipomas
Ganglion cyssts
Vascular stuff - aneurysms
Fibromatosis
Bone tumours
Other things ptx might do causing radial nerve injury
improper use of axillary crutches
Other things we might do causing radial nerve injury
prolonged use of upper arm tourniquets, lateral
posterior intramuscular injections into the arm, and scar following surgery in the posterior arm
Ptx from TB area with TB osteomyelitis/nearby lymphadenitis has Radial nerve neuropathy
Maybe its because of the TB
Unusual infection causing radial nerve injury
HSV
Radial nerve entrapment or chronic RN pain not responding to treatment
Hydrodissection done under US (usually saline, sometime steroids)
