Table 3. Summary of radiological abnormalities recorded on postoperative brain scan.

Radiological abnormalities	Case number
	1	2	3	4	5	6	7	8
Estimated % resection of tumor	90%	GTR	90%	GTR	GTR	GTR	GTR	Biopsy – no resection
DWI abnormalities surround the lesion (cm)	5	1.5	Small patchy foci	Small patchy foci	None	None	2	N/A
Enhancement with Gd at margins	No	No	No	No	No	No	Yes	Yes

Gd = gadolinium; GTR = gross total resection – identified radiologically; DWI = diffusion weighted imaging.
