Diagnostic Accuracy of Focused Appendiceal CT in Clinically Equivocal Cases of Acute Appendicitis

Abstract

Focused appendiceal CT in which oral contrast material is used alone yields high levels of accuracy in clinically equivocal cases of acute appendicitis.

Ultrasonography Evaluation for Predominant Content of Appendix

“…(3) The usefulness of high frequency probe and graded compression method has a high diagnostic value for acute appendicitis. (4,5) Superiority of Computed tomography compared to Ultrasonography is overemphasised by many studies (6,7,8,9,10,11) possibly because ultrasonography instrumentation was not very well developed at that time.…”

Radiological-pathological Discordance in a Patient With Appendicitis Findings on Computed Tomography

“…Periapandisit apendiks çevresi yağlı dokuların ve apendiksin serozal yüzeyinin pelvik inflamatuar hastalık, divertikülit ve ileit benzeri apendiks dışı nedenler ile inflamasyonu için kullanı-lan histopatolojik bir terimdir ve negatif appendektomi sebeplerinden biridir (4,5). Safra yollarındaki perforasyon sonrası serozal yüzey-ler için oldukça irritan olan safra kaçağına bağlı akut batın tablosu ve akut perforasyonlarda peritonit oluşabilir (6) ve buna bağlı tomografide olgumuzda olduğu gibi akut apandisiti taklit eden bulgulara rastlanabilir.…”

Impact of the Use of Contrast-Enhanced Multidetector CT for Acute Appendicitis: A Prospective Comparison with the Alvarado Score

“…This focused CT approach revealed high sensitivity and specificity similar to those of non-focused CT approaches for the confirmation or exclusion of appendicitis and had the advantage of minimizing the time required for diagnosis and the amount of radiation exposure (15 18). However, a limited evaluation of the intraabdominal pathological conditions resulting from a limited scanning field of view is the major reason that this approach is only rarely used (13,16,17). Our contrast-enhanced MDCT protocol included a focused arterial phase composed of thin sectioning slices of 3 mm around the appendix and the non-focused portal phase was composed of conventional sectioning slices of 5 mm over the entire abdomen in order to reach an alternative diagnosis without the use of any internal contrast material.…”
