There are a number of abnormalities,
associated with secondary psychosis
Let's talk about MRI
Primary role
Goal
Excluding structural abnormalities,
that may be underlying in a secondary cause
No it is not used to diagnose schizophrenia,
and related primary psychotic disorders
Debate?
Should MRI be offered to patients in routine,
presenting with psychosis?
Some research suggests in the 2008
NICA technology appraisal,
it should not be routine,
unless a clinical suspicion,
of secondary cause
Contrasting guidelines,
in Australia and Germany
recommend MRI as a routine,
Clinical high,
for all patients that are presenting,
with a first episode of psychosis representing
Let's get complicated
No consensus
around about the key,
structural abnormalities,
you see,
of what should be excluded,
when reports of MRI
are with the focused sky,
Hyperintensities most common abnormality,
patients presenting with first episode psychosis
Clinically white matter another common form
T2 FLAIR
refers to areas of increased brightness T2-weighted MRI scan
CT and MRI
Advantages and disadvantages
CT can be a few minutes
Several minutes for an MRI
CT not so claustrophobic in the environment
Medical high
More widely used,
in less well resourced scenes
Out of hours,
more brain powers
Emergency presentation,
CT generation,
ionizing radiation,
MRI no relation
Repeat no safety risk
Enhanced sensitivity,
detecting clinically relevant,
brain abnormalities,
that are not for CT
Clinical presentation,
even minor detected,
in the imaging relation
MRI definitely preferable,
for first episode psychosis presentation
In your absence,
Clinical relevance,
uses CT
to see presentations,
of first episode psychosis,
perhaps emergency situation diagnosis
