Abstract
Background and purpose
Perfusion Computed Tomography (CTp) is an imaging technique which allows
quantitative and qualitative evaluation of tissue perfusion through dynamic
CT acquisitions. Since CTp is still considered a research tool in the field
of abdominal imaging, the aim of this work is to provide a systematic
summary of the current literature on CTp in the abdominal region to clarify
the role of this technique for abdominal cancer applications.
Materials and Methods
A systematic literature search of PubMed, Web of Science, and Scopus was
performed to identify original articles involving the use of CTp for
clinical applications in abdominal cancer since 2011. Studies were included
if they reported original data on CTp and investigated the clinical
applications of CTp in abdominal cancer.
Results
Fifty-seven studies were finally included in the study. Most of the included
articles (33/57) dealt with CTp at the level of the liver, while a low
number of studies investigated CTp for oncologic diseases involving UGI
tract (8/57), pancreas (8/57), kidneys (3/57), and colon–rectum (5/57).
Conclusions
Our study revealed that CTp could be a valuable functional imaging tool in
the field of abdominal oncology, particularly as a biomarker for monitoring
the response to anti-tumoral treatment.
