Object radiography contrived to illustrate basic principles.

To add variety to radiologic teaching and to lower view box monotony, we imaged ordinary objects in circumstances that illustrate--caricature might be a better word--basic pathologic and radiologic principles. We tried to make each object image an interpretation challenge amenable to solution through logical application of such principles, and the result has added spice to our teaching sessions. Yet object radiography can play only an ancillary teaching role; we use it sparingly and always in combination with cases that illustrate the principles in question. Otherwise, the technique itself may add to the monotony it is designed to combat.

Clinical radiographs of the cadaver as a teaching aid in anatomy.

The use of clinical histories and radiographs of cadavers as a method for teaching anatomy was explored. This method was found to generate student interest in both anatomy and radiology, to make anatomy clinically relevant, and to supplement the laboratory manual by guiding the student through the dissection of medically or surgically complicated cases. It is an effective and workable method that is easily implemented and virtually cost free.

Tubes, wires, and rods seen in chest roentgenograms.

Different devices are seen on chest roentgenograms everyday. The gamut of metallic density shadows include sutures, surgical clips, staples, cardiac valve prosthesis, wires, and plates. Tubes and catheters are recognized when metallic wires or barium are incorporated in their walls. The number of devices is ever growing and with them complications grow. The radiologist may be the first to detect these complications. This article endeavors to review briefly a small number of these devices and their complications. References are provided for the avid reader.

Some uncommon lower mediastinal densities: a pictorial essay.

Despite CT and NMR, plain radiography still plays a major role in the diagnosis of mediastinal disease. In this article, the value and limitations of conventional techniques in the diagnosis of some unusual lesions of the lower mediastinum are demonstrated.

Neoplastic complications of neurofibromatosis.

Neurofibromatosis associated with secondary neoplasms is discussed. Neurosarcomas are the most common and most malignant secondary tumors in neurofibromatosis. Any sudden growth in a peripheral tumor in this disease should alert the physician to the possibility of malignant change and the need for biopsy. Only by early diagnosis and adequate excision can some of these patients be saved.

Photographic method of recording radiation fields using the localizer light for illumination.

By interposing a camera with a fish-eye lens between the collimator and the illuminated field, radiotherapy ports can be recorded using the localizer light for illumination. An acrylic mold of the camera was used to maintain alignment and immobilization during the necessarily long exposures. The authors consider this a very objective and accurate method of recording the topography of radiation ports.
