• "Coagulation concepts update"

O'Connor SD, Taylor AJ, Williams EC, et al., AJR Am J Roentgenol 193 (6): 1656-1664 Dec 2009. The basic tools for coagulation assessment have not changed; however, results from subspecialty research have suggested ways in which the use of these tools can be modified and streamlined to safely reduce time and expense for the patient and the health care system.

• "Esophageal clearance patterns in normal older adults as documented with videofluoroscopic esophagram"

Jou J, Radowsky J, Gangnon R, et al., Gastroenterol Res Pract. 965062 2009. Normal esophageal bolus transport in asymptomatic healthy older adults has not been well defined, potentially leading to ambiguity in differentiating esophageal swallowing patterns of dysphagic and healthy individuals. Pubmed/NLM.

• "A noninvasive imaging technique to evaluate therapeutic efficacy after injection of n-butyl-2- cyanoacrylate tissue adhesive into gastric varices: a case report"

Spier BJ, Taylor AJ, Pfau PR, et al., Can J Gastroenterol 23 (6): 412-414 Jun 2009. This represents the first reported use of MDCT IV portography in the evaluation of treatment adequacy in a patient with gastric varices treated with n-butyl-2-cyanoacrylate. Pubmed/NLM.

• "Unsuspected extracolonic findings at screening CT colonography: clinical and economic impact"

Pickhardt PJ, Hanson ME, Vanness DJ, et al., Radiology 249 (1): 151-159 Oct 2008. Detection of relevant unsuspected extracolonic disease at CT colonographic screening is not rare, accounting for a relatively large percentage of cases in which additional workup was recommended. Judicious handling of potential extracolonic findings is warranted to balance the cost of additional workup against the potential for early detection of important disease, because many findings will prove to be of no clinical consequence.
