Ancient Egypt had an advanced elaborate medical education and practice ruled by a competent bureaucracy that apprenticed physicians to be practicing healers. In modern history, the Faculty of Medicine at Cairo University (Kasr Al-Ainy), established in 1827, continues the glory of Egypt in medical education as one of the biggest and oldest medical schools in Africa and the Middle East. Its central Radiology Department, with its total 77 radiologists, is responsible for clinical services as well as for providing multiple calibre radiology education programs for about 100 trainees annually from Egypt and neighbouring countries. Radiology education programs are planned for radiology residents to obtain master’s degree (M.Sc.), for assistant lecturers to obtain medical doctorate (M.D.) and for visitor trainees. Objectives of radiology education programs include knowledge, practical skills, intellectual capabilities and communications with medical societies and communities. Trainees are assessed to determine if learning objectives have been fulfilled on a daily, weekly and biannual basis. Radiology education programs are measured for professional performance through the university’s self-assessment studies; national assessment is measured through the National Authority for Quality Assurance and Accreditation in Education (NAQAAE), Egypt, and international assessment is measured through the World Federation for Medical Education (WFME).

MRI has been increasingly used for detailed visualization of the fetus in utero as well as pregnancy structures. Yet, the familiarity of radiologists and clinicians with fetal MRI is still limited. This article provides a practical approach to fetal MR imaging. Fetal MRI is an interactive scanning of the moving fetus owed to the use of fast sequences. Single-shot fast spin-echo (SSFSE) T2-weighted imaging is a standard sequence. T1-weighted sequences are primarily used to demonstrate fat, calcification and hemorrhage. Balanced steady-state freeprecession (SSFP), are beneficial in demonstrating fetal structures as the heart and vessels. Diffusion weighted imaging (DWI), MR spectroscopy (MRS), and diffusion tensor imaging (DTI) have potential applications in fetal imaging. Knowing the developing fetal MR anatomy is essential to detect abnormalities. MR evaluation of the developing fetal brain should include recognition of the multilayered-appearance of the cerebral parenchyma, knowledge of the timing of sulci appearance, myelination and changes in ventricular size. With advanced gestation, fetal organs as lungs and kidneys show significant changes in volume and T2-signal. Through a systematic approach, the normal anatomy of the developing fetus is shown to contrast with a wide spectrum of fetal disorders. The abnormalities displayed are graded in severity from simple common lesions to more complex rare cases. Complete fetal MRI is fulfilled by careful evaluation of the placenta, umbilical cord and amniotic cavity. Accurate interpretation of fetal MRI can provide valuable information that helps prenatal counseling, facilitate management decisions, guide therapy, and support research studies.

The mummy of King Amenhotep I (18th Dynasty c.1525-1504 BC) was reburied by the 21st Dynasty priests at Deir el-Bahari Royal Cache. In 1881 the mummy was found fully wrapped and was one of few royal mummies that have not been unwrapped in modern times. We hypothesized that non-invasive digital unwrapping using CT would provide insights on the physical appearance, health, cause of death, and mummification style of the mummy of King Amenhotep I. We examined the mummy with CT and generated two- and three-dimensional images for the head mask, bandages, and the virtually unwrapped mummy. CT enabled the visualization of the face of Amenhotep I who died around the age of 35 years. The teeth had minimal attrition. There was no CT evidence of pathological changes or cause of death. The body has been eviscerated a vertical left flank incision. The heart is seen in the left hemithorax with an overlying amulet. The brain has not been removed. The mummy has 30 amulets/jewelry pieces including a beaded metallic (likely gold) girdle. The mummy suffered from multiple postmortem injuries likely inflicted by tomb robbers that have been likely treated by 21st Dynasty embalmers. These included fixing the detached head and neck to the body with a resin-treated linen band; covering a defect in the anterior abdominal wall with a band and placing two amulets beneath; placement of the detached left upper limb beside the body and wrapping it to the body. The transversely oriented right forearm is individually wrapped, likely representing the original 18th Dynasty mummification and considered the first known New Kingdom mummy with crossed arms at the chest. The head mask is made of cartonnage and has inlaid stone eyes. The digital unwrapping of the mummy of Amenhotep I using CT sets a unique opportunity to reveal the physical features of the King non-invasively, understand the mummification style early in the 18th Dynasty, and the reburial intervention style by 21st Dynasty embalmers. This study may make us gain confidence in the goodwill of the reburial project of the Royal mummies by the 21st dynasty priests.
