Additional Diagnostic Value of Unenhanced Computed Tomography plus Diffusion-Weighted Imaging Combined with Routine Magnetic Resonance Imaging Findings of Early-Stage Gliblastoma

Table 1

Imaging findings in eight patients with early-stage glioblastoma.

Patient/age (year)/sex		CT		MR imaging
	Location	Attenuation	T1-weighted image	T2-weighted image	Diffusion-weighted imaging	Enhancement
1/36/M	Right temporal lobe	A	HYPO	Inhomogeneous HYP	A	No
2/57/F	Right temporal and occipital lobe	A	MIX	Inhomogeneous HYP	B	No
3/41/F	Right temporal lobe and hippocampus	B	ISO	Inhomogeneous HYP	C	No
4/65/M	Bilateral temporal lobe and hippocampus	A	ISO	Homogeneous HYP	No examination	No
5/43/F	Right temporal lobe	A	HYPO	Inhomogeneous HYP	C	No
6/71/F	Brainstem and cerebellum	A	HYPO	Inhomogeneous HYP	B	No
7/62/F	Left temporal lobe	A	HYPO	Inhomogeneous HYP	B	No
8/67/M	Left temporal lobe	A	HYPO	Homogeneous HYP	C	No

CT Attenuation: A, hypoattenuated lesion with hyperattenuated region; B, hypoattenuated lesion with isoattenuated region. Diffusion-weighted imaging: A, hyperintense lesion; B, isointense lesion with hyperintense region; C, isointense lesion with peritumoral hyperintensity. ISO, isointense; HYP, hyperintense; HYPO, hypointense; MIX, mixed isointensity and hypointensity.
