MRCP: examining the obstructed bile duct
| The first 150 words of the full text of this article appear below. |
Clinicians have been taken aback by the rapid developments in
magnetic resonance cholangiopancreatography (MRCP), including elegant
computer reconstructions of the biliary and pancreatic ducts from
images acquired by magnetic resonance scanning. Pioneer endoscopists of
the late 1970s and 1980s struggled to produce diagnostic retrograde
cholangiograms, at some risk to the patient, and now in the 1990s
images of almost comparable quality can be produced without an
endoscope, without contrast and even without radiation. The technical
aspects are so complex that the non-radiologist is unlikely to
understand the variations such as T2 spin weighting, half-Fourier
acquisition single-shot turbo spin-echo (HASTE) sequences, and rapid
acquisition with relaxation enhancement (RARE). For those wishing to
try, they are clearly covered in a recent leading article in this
journal.1 Yet the technique is so beguiling and the images
so similar to those obtained with contrast injection that clinicians
will have to be wary of serious
