New paleoradiological analysis of the Mummy of Kaipamau from Archeological Museum in Zagreb, Croatia

The Egyptian collection in Archeological Museum in Zagreb contains 5 whole Egyptian mummies. One of the exhibits is the anthropomorphic coffin with a mummy and a cartonnage of a woman named Kaipamau, Amon’s priest. Sarcophagus is dated in Late period, 22nd Libyan Dynasty (945-715). A mummy was scanned in Dubrava University Hospital, University Department of Diagnostic and Interventional Radiology Zagreb, Croatia. CT scan was done using 16x0.75 collimation using a MDCT unit with 16 rows of detectors. A three dimensional MRI scan, spoiled gradient echo based ultrashort echo time sequence was performed on a 1.5 Tesla scanner. The echo time was set to 0.07 ms, repetition time to 15 ms and the flip angle to 45⁰. 40000 radial projections were used for reconstruction of 256 slices of 1.3x1.3x1.3mm3 isotropic resolution. According to anthropological analysis mummy is female and at least 40 years old at time of death. Nasal septum is deviated to the left and obstructive sleep apnea could be suggested. Persistent frontal suture (metopic) is observed on frontal bone. Remnants of aorta and heart are seen in thorax and incomplete evisceration in abdomen is observed. CT investigation has given additional information as interesting anomaly is detected (metopic suture). Magnetic resonance, used only several times before in scientific studies of mummy, has provided additional data in analysis of results, as no signal was detected inside of abdominal cavity. The absence of visceral packages could speak about different dating of mummy and sarcophagus.
