    Notes: Abstract  Purpose. The prevertebral soft tissue measurement is commonly used for assessing prevertebral pathology such as abscesses or hematomas after injury. Very few references concerning the ratio of retrotracheal thickness to C5 diameter are available in the literature. The purpose of this study was to measure the normal soft tissue thickness at the C5 level of the neck and to establish the normal ratio of retrotracheal soft tissue thickness to the diameter of C5 for daily use. Design and patients. We measured soft tissue thickness in the neck of 54 normal subjects and calculated the mean and standard deviation. Results and conclusion. Using mean plus one standard deviation the maximum retrocricoid soft tissue thickness was 0.7×C5 diameter and maximum retrotracheal thickness was 1.0×C5 diameter. Soft tissue thickness that exceeds this limit must be studied further for signs of potential disease.

    Notes: Abstract Endometriosis is a common disease in young women being evaluated for infertility. Although endometriosis may cause tubal abnormalities on hysterosal-pingography, efficacy of radiographic evaluation in this disease is not clear. We reviewed the radiographic and laparoscopic examinations in 50 women being studied for infertility. Laparoscopy was normal in 15 women and showed endometriosis in 35 patients. Endometriosis was staged at laparoscopy using the classification of the American Fertility Society. Radiographic examinations were reviewed blindly and tubal status noted in each patient. Criteria for tubal abnormality included incomplete or absent filling and ampullary dilatation or convolution. Radiographic efficacy was determined by correlating the tubal appearance to the severity and location of endometriosis. A total of 98 tubes were correlated but only 10 (10%) were felt to be involved by endometriosis based on laparoscopic findings. Radiologic sensitivity was 40% (4 of 10) and specificity was 83% (73 of 88). Positive predictive value was 21% (4 of 19) due to 15 false-positive diagnoses in tubes uninvolved by endometriosis. In conclusion, endometriosis, regardless of its severity, rarely causes radiographic abnormalities on hysterosalpingography because of the location of disease in the pelvis.

    Interureteric ridge edema: incidence and etiology (1995)
    Springer
    Abdominal imaging 20 (1995), S. 368-370

    Notes: Abstract Background Interureteric ridge edema may be seen at intravenous urography (IVU) and is related to acute lower ureteral obstruction, trauma, or calculi. The purpose of this study was to explore the relationship between interureteric ridge edema and acute distal ureteral obstruction caused by ureteral calculi. Methods A total of 338 patients who had IVU for various indications during a 6-month period were reviewed for the presence of interureteric ridge edema. Results Interureteric ridge edema was seen in 12 (4%) of 338 patients, all with acute lower ureteral obstruction from stones. Interureteric ridge edema was best demonstrated with the partially filled bladder film or postvoid bladder film in all cases. Conclusion Interureteric ridge edema is most commonly caused by stone-induced distal ureteral obstruction and is less commonly seen with recent passage of a stone or other etiologies. Interureteric ridge edema was present in 26% of patients with acute lower ureteral obstruction.
