A CT patient study contains 500 images. Approximately how much storage space is required?

A) 250 MB

B) 500 MB

C) 2000MB

D) 5000MB

A) 250 MB

512pixels x 512pixels x 2 bytes/pixel x 500 images= 262 MB

The interface standard primarily used for transferring imaging procedure names between different information systems is called

A) CAT5

B) DICOM

C) HL7

D) IHE

C) HL7

A PACS system typically includes

A) Archive server

B) Web server

C) Database server

D) All of the above

Models such as RadLex are designed to enable

A) Accurate reporting of pathology

B) Speedy reporting of patient diagnosis

C) Consistent terminology in patient reports

D) Short and concise reporting of findings

C) Consistent terminology in patient reports

RAID5 storage is employed in a PACS archive because it provides

A) Duplicate storage of all files

B) A means to rebuild data if a single disk fails

C) A removable medium for daily off site storage

D) A low cost storage option

B) A means to rebuild data if a single disk fails

RAID is Redundant Array of Independent Disks. Data is stored in a redundant fashion, so that failure of a disk drive will not lead to data loss.

The most likely reason for inconsistent patient ID information between the RIS database and the DICOM header would be

A) Modality worklist function was not used

B) Patient information was updated prior to scheduling the study

C) A DICOM transmission error occurred

D) The wrong ID number was dictated by the radiologist

A) Modality worklist function was not used

An example of true structured reporting is

A) The DICOM compliance statement

B) Productivity reports from analyzing PACS data

C) BI-RADS mammography reporting

D) IHE profiles of imaging workflow

C) BI-RADS mammography reporting

Decreased processing load is placed on the PACS server by use of

A) Thin client workstations

B) SAN storage technology

C) IHE profiles

D) DICOM compliant devices

B) SAN storage technology

Both network attached storage (NAS) and storage area networks (SAN) serve data over a network connection, reducing the processing load on the PACS server.

Compression of acquired MRI images

A) Is not allowed for diagnostic reads

B) Is not allowed for image long term storage

C) Is allowed if approved by a radiologist

D) Is allowed as long as it’s less than 20:1

C) Is allowed if approved by a radiologist

10.

The HIPAA law requires for patient data

A) A review of the facilities current data integrity practices

B) Documentation of procedures for disposal of electronic media
