James Penn

The second mummy evaluated was from Reading, Pennsylvania, and identified as James Penn (Figure 3.61). The individual was purportedly embalmed with formaldehyde in 1895, making him one of the earlier cases of formaldehyde embalming in the United States. The mummy was imaged on a 1.5 T Achieva Scanner (Philips Medical Systems) using the Sense body coil and 16-channel head coil. As with the previous specimen, the scanner was unable to tune in on the signal automatically. Manual tuning on this system was also ineffective, so it was necessary to load the coil by placing several IV bags containing normal saline around the head and body of the mummy (Figure 3.62). The addition of the saline provided the mobile protons necessary to tune the scanner, and once tuned the scans were completed without further problems. T1 images were obtained in 7-mm-thick sections from multiple planes in the head, body, and extremities. Although

thick sections would not provide detailed images, it would indicate the location of residual fat. James Penn was remarkably well preserved, and his internal organs were intact per CT scanning.
