things of notice

• looked (and touched) coronary angioplasty stents - very flexible and observed the difference between deployed and non-deployed state
• looked at valvuloplasty stents
• X-rays images of old age can show osteoporosis, and also the cardio-phrenic angle will become blunt due to calcification.
• CT vs MRI - which to use for urgent cases? CT, because it is done fast.
• it irritates the radiologist when other doctors order for a radiological investigation without a clinical reference. also doctors do have horrible handwriting. clinical reference may be given but with illegible handwriting.
• when you take a CT-scan, the computer can render it and you can see it in 3-D. the 3-D images can be rotated in 3 different windows simultaneously, which enables extensive visualization of internal organs.
• Ultrasonography is an imaging investigation that requires a lot of skill - which means that the competence of the person carrying out will determine the accuracy of the investigation and hence, diagnosis. same goes with CT of coronary vessels with contrast dyes.
