 64
Slice MDCT |
| By Dr. Mariko Ehara |
Today, the imaging technology
of diagnosis has been strikingly advanced and its
accuracy has also been enhanced to be used in the
current medical practice.
Along with its innovative technological advancement,
a device that offers clear images less invasively
is strongly demanded. Dr. Mariko Ehara at Toyohashi
Heart Center introduced the latest 64-slice CT.
Multi slice system has been advanced from four slices
to eight slices and shift to sixteen slices to sixty-four
slices. A high rotational speed accomplished by
the latest technology has improved time and spatial
resolutions.
Dr. Ehara demonstrated the technological innovation
of 64-slice CT in the field of cardiology. This
system introduced in the Japan’s first. Analyzing
diagnostic imaging in the field of coronary angiography
is formerly considered to be difficult because the
beating heart creates a motion artifact. However,
a diagnosis using the latest multi-slice CT can
prevent the presence of motion artifact and potentially
offer clear image on beating heart.
5ml/sec contrast media is required. Diagnosis takes
approximately 10 seconds; thus the total amount
of contrast media required is ranging between 50-100ml.
Not only the highest 64-slice CT collects enormous
data at the short period of time, but it also manages
these dada at the highest speed.
The screening of coronary artery disease using less
invasive 64-slice CT will become a routine practice
in near future. However, there is no adequate evidence
that the tool prevails over a standard angiography.
Assessment of lesion characteristics on intracoronary
plaque and follow up after the implantation of coronary
stent are next steps to be considered the usage
of this diagnostic tool.
Dr. Ehara and her colleagues currently investigate
the assessment f stent structure and plaque characteristics
within the stent. Results of further investigations
will be announced in near future. |
