Subject	Age/Gender	Thrombus Site	Thrombus Age (days) at Time of CT	HU (Mean = 77)	HCT%	H:H Ratio (Mean = 2.20)	HGB
1	29/M	SSS	3	92	46	2.0	15.9
2	26/F	SSS	4	86	36.2	2.38	11.8
3	39/M	SSS, torcula	7	83	44.6	1.86	15.4
4	53/F	Straight, bilateral transverse, sigmoid, torcula, SSS	3	78	37.2	2.10	12.8
5	41/F	Left transverse, sigmoid	3	74	32.6	2.27	11.3
6	41/M	SSS, left transverse	1	76	33.3	2.28	11.1

8	18/M	SSS, straight, bilateral transverse	12	46	25.0	1.84	8.6

Note:—Age is defined as the estimated time interval between onset of symptoms from thrombosis and measuring attenuation of thrombosis on CT.
