    Notes: Abstract  Objective. Transposition of the pisiform bone is an operative treatment for lunatomalacia. The postoperative viability of the transposed pisiform bone is difficult to assess. The purpose of the study was to evaluate the utility of MRI for postoperative assessment of viability of the pisiform and lunate bones. Design and patients. Six patients who underwent transposition of the pisiform for treatment of lunatomalacia, were assessed pre- and postoperatively with conventional radiographs (including tomography), CT and MRI. Results. Conventional radiographs, conventional tomograms and CT were all useful in demonstrating the location of the transposed pisiform. CT showed the transposed pisiform without superposition. However, neither CT nor conventional techniques provided information regarding viability of the pisiform. In all patients investigated in the first year following surgery, T1-weighted MR images showed high signal intensity in the transposed bones. In all patients investigated after 1 year, the signal intensity decreased to an intermediate level on T1-weighted images. Enhancement following contrast medium administration in the transposed pisiform and the lunate was noted in all patients, indicative of viability. Conclusion. Contrast-enhanced MRI is able to provide important information regarding the viability of the transposed pisiform and the remaining parts of the lunate. Thus, contrast-enhanced MRI provides an improved means of postoperative assessment regarding short-term follow-up following pisiform transposition. In the long-term follow-up conventional radiography and CT may be equal to MRI in showing increasing sclerosis and/or fragmentation.

    Description / Table of Contents: Summary A general review of the results and technique of intraarterial chemotherapy in cases of breast cancer is given. The remission rate for untreated primary tumors is nearly 100%, for completely treated local relapses approximately 70%. The complication rate is quite low using an intraarterial well-tolerated cytostatic agent such as mitoxantrone. However, thromboembolism of the vertebral artery facing the internal mammary artery may occur. The indication for intraarterial chemotherapy should always be set by an interdisciplinary board.
    Notes: Zusammenfassung In der vorliegenden Arbeit werden Technik und Ergebnisse der intraarteriellen Chemotherapie beim Mammakarzinom übersichtsartig beschrieben. Die Remissionsraten für einen unbehandelten Primärtumor liegen bei nahezu 100%, beim ausbehandelten Lokalrezidiv bei ca. 70%. Unter Verwendung eines intraarteriell gut verträglichen Zytostatikums wie Mitoxantron sind die Komplikationsraten gering, zu fürchten ist vor allem eine Thromboembolie in die gegenüber der A. mammaria interna gelegene A. vertebralis. Die Indikation zur intraarteriellen Chemotherapie sollte immer interdisziplinär gestellt werden.
