This value set includes codes based on the following rules:

• Include these codes as defined in http://dicom.nema.org/resources/ontology/DCM

  Code	Display	Definition
  130582	Unwanted subtraction images	Extra subtraction image sets are present that are incorrect or confusing.
  130581	Subtraction image missing	The study lacks a sufficient set of subtraction images.
  130580	Inadequate contrast enhancement	Contrast enhancement observed in the image is not sufficient for the purpose of the acquisition.
  130586	Distortion artifact in the area of interest	Geometric distortions are present in the image, and are affecting the area of interest in the image.
  130585	Expected ADC map is missing	Apparent Diffusion parametric map image is missing, but was expected.
  130584	Severe distortion in the area of interest	Severe geometric distortions are present in the image, and are affecting the area of interest in the image.
  130583	Expected b-value is missing	Diffusion-weighted MR image obtained with an expected b-value is not present.
  130579	Poor contrast timing	Timing of the contrast injection relative to the timing of the image acquisition was not properly selected.
  130578	Poor SNR	Signal-to-noise characteristics are insufficient for the purpose of the acquisition.
  130577	Poor FOV selection	Choice of Field of View size or position is not fit for the purpose of the acquisition.
  130576	Anatomy coverage incomplete	Coverage of the imaged anatomy is not complete.
