Sectional
Relating to an image that looks like a thin, sectional slice through the patient. Most common in CT, MRI and SPECT is the cross-sectional (= axial or transverse) slice, but in MRI sagittal (="profile"), coronal (="frontal") and even angled sections/slices are also used, whereas in ultrasound sections may be at any angle, and are usually wedge shaped.
