As well as voxel-based morphometry, a novel voxel-based quantitative analysis of T1 - and T2 -weighted spin-echo (T1w and T2w) MRI signal level was performed. Severity scores included the Bell CFS disability scale and scores based on the 10 most common CFS symptoms.

If the transmit gain setting is decreased, the required length of the 90o and 180o pulse will increase. 2.5 Capacitance Determines the resonant frequency of the B1 coil 10nF ( 4.4 -17.15nF) Receive gain Controls the degree of amplification of the received signal. If clipping occurs on the FID signal, reduce the receive gain. (0-10) 22 19

Epicondylitis (tennis and golfers’ elbow)
Most authors agree there is no need for further imaging; however, MRI shows decreased signal on T1 and T2 (consistent with fact this is not an inflammatory condition). Other studies. EPS (electrophysiological) may be considered if there is any indication of ulnar nerve involvement or in the differential diagnosis of radial tunnel syndrome.

Decreased signal on both T1 and T2. Correlate with extensive bony sclerosis on plain radiographs. Histological examination shows dense woven bone; hence, no marrow to produce MRI signal.
