REPRESENTATIVE CASE STUDIES
The purpose of reviewing representative
cases is to evaluate the interpretive and technical quality
of the laboratory as a whole. In order to do this, it is necessary
for the ICACTL reviewers to evaluate representative cases from
as many medical and technical staff members interpreting
or performing any CT examinations in the laboratory as possible.
The cases submitted must be contemporary (i.e., performed with
current personnel on current equipment). Failure to provide
representative cases from the current personnel may result in
delay of accreditation and request for additional case studies.
The number of cases to be submitted per laboratory
is dependent upon the type of accreditation requested (i.e.:
Cardiovascular, Neuroimaging, other CTA, Whole Body CT) and
the number of CT scanners within the laboratory. All case
studies selected must have been performed within the twelve
(12) months immediately prior to submission of the application.
Each case must include a sufficient number of images to
support the final diagnosis and a signed copy of the final report.
A copy of any worksheets and/or preliminary reports, if generated,
should be submitted as well.
The following information must be on or included
with all submitted CDs, DVDs or filmed images:
- laboratory name
- date of the examination
- patient age or date of birth
- slice thickness
|
- patient ID
- field of view
- acquisition
- size scale
|
Guidelines for case selection and organizing
cases to be submitted:
1. Case selection is CT scanner dependent
and lab specific. You must submit the required sample cases
for each scanner used clinically in your laboratory.
2. The case studies must include a
copy of the final report and be representative of as many
medical and technical staff members interpreting or performing
any CT examinations in the laboratory as possible.
3. The case studies must be submitted
by film, CD, or DVD* (with viewer or reader installed) for
those areas in which accreditation is being requested . (Please
check the CD or DVD on an alternate computer to ensure that
it can be opened and viewed.)
*Comment: Cardiac case studies and all CTA studies
are to be submitted on CD or DVD only, with viewer or reader
installed.
4. If your laboratory does not perform
all of the case studies required as outlined, please submit
those meeting the requirements, as well as additional studies
relevant to your laboratory's practice, to equal five (5)
cases total.
5. All hard copy documents including
CDs and DVDs must be labeled with a unique patient ID (i.e.:
patient name, laboratory tracking number, etc.), the type
of examination and the type of hard copy
being submitted. Do not submit black and white photocopied
images.
6. As explained in the General Instructions,
two complete copies of the application AND representative
cases are to be submitted. All hard copy documents, reports,
films, CDs, DVDs, etc., are to be submitted in duplicate as
well.
Note: All material submitted to the
ICACTL will be handled with strict confidentiality.
CASE STUDY REQUIREMENTS:
- CARDIOVASCULAR CTA ACCREDITATION

be submitted on CD or DVD, with viewer installed and
instructions as necessary; include only those phases
reconstructed, indicate phase(s) and field of view reconstructions
used for interpretation.

in a normal patient
Case Two: 1 cardiac examination in a patient with non-obstructive
CAD
Case Three: 1 cardiac examination in a patient with
obstructive CAD
Case Four: 1 complete gated cine cardiac examination
in a patient with LV dysfunction secondary to myocardial
infarction
Case Five: 1 cardiac examination in a patient
with prior coronary bypass graft
- OTHER CTA
To be submitted on CD or DVD only with viewer installed.
Case One: 1 extracranial carotid artery axial,
coronal, sagittal, and 3-D reconstructed views --
1-2 mm cuts

aortic imaging axial, coronal, sagittal, and 3-D reconstructed
