Heartburn. The role of radiology.
There is currently controversy as to the importance of the radiologic demonstration of a hiatal hernia, reflux, or both as the explanation of heartburn. It is clear, however, that clinical-radiologic correlation requires additional observations such as the straightness of the potential path for reflux, the presence of a contractile esophagogastric region, the degree of extrinsic compression of the cuff of the stomach within the hiatus, the size of the hernia, and the peristaltic activity of the body of the esophagus. Vigorous or water-swallowing maneuvers to demonstrate reflux are unreliable in individual cases. Of importance is the concept that the so-called patulous cardia, or effaced abdominal esophagus or widened or absent "submerged segment," is a variety of sliding hiatal hernia that is often neglected radiologically but may be of considerable clinical significance.
A simple ultrasound guide for needle puncture.
A method of ultrasound directed needle puncture using a clamp and a guide block is described. It eliminates the need for an aspiration biopsy transducer and has proved to be simple, accurate, and inexpensive.
Feasibility of coronal views in computed scanning of the head.
With some models of computerized scanners, it is possible to obtain not only axial, but also coronal tomograms. This is feasible because a water bag is not used and limited tilting capacity is built into the gantry. The head is extended and the central ray directed perpendicularly to the base of the skull. The resulting views, orthogonal to the conventional axial views, furnish important complementary information.
A pulmonary venous indentation on the esophagus-a normal variant.
An extrinsic indentation on the anterior left wall of the esophagus, about 4-5 cm below the carina, is a relatively common finding and should be considered a normal variant, although rarely it may be due to an aberrant insertion of a pulmonary vein into the left atrium. The indentation is best seen in a steep left posterior oblique horizontal position. In most cases it is caused by pressure of the left inferior pulmonary vein or a common confluence of the left pulmonary veins near the insertion into the left atrium. Generally, it does not cause any symptoms and should not be mistaken for a mediastinal mass.
