Table 1 Technical parameters for WBLDCT exams in MM

From: Recommendations for acquisition, interpretation and reporting of whole body low dose CT in patients with multiple myeloma and other plasma cell disorders: a report of the IMWG Bone Working Group

Number of detector rows

16 or more

Scan coverage

Cranial vault to proximal tibial metaphysis (include humeri in the field of view)

Tube voltage(kV)/time-current product (mAs)

120/50–70a

Collimation

0.5–1.5 mm

Reconstruction convolution kernel

Sharp, high-frequency (bone) and smooth (soft tissue). Alternatively, one middle-frequency kernel for all images

Iterative reconstruction algorithms

Yes (to reduce image noise and streak artifacts)

Thickness/increment of axial slices

2/1 mm or 3/1.5 mm

Multiplanar Reconstructions (MPRs)

Yes (sagittal, coronal and parallel to long axis of proximal limbs).

  1. aDifferent tube parameters (e.g., 140/14–25 or a low voltage approach) are acceptable as long as they produce images of diagnostic quality with low effective patient dose
