     Bio-Imaging  Technologies,  Inc. (the "Company")  hereby amends its Current
Report on Form 8-K dated April 15, 2002 filed with the  Securities  and Exchange
Commission on April 17, 2002 to file an amended letter from Arthur  Andersen LLP
("Arthur  Andersen").  As reported by the Company in such Current Report on Form
8-K, on April 15, 2002, the Company determined to dismiss Arthur Andersen as its
independent  auditors and to engage the services of  PricewaterhouseCoopers  LLP
("PWC") as its new  independent  auditors.  The change in auditors was effective
April 15,  2002.  This  determination  followed the  Company's  decision to seek
proposals from independent  accountants to audit the financial statements of the
Company,  and  was  approved  by the  Company's  Board  of  Directors  upon  the
recommendation of its audit committee.  PWC will audit the financial  statements
of the  Company  for the fiscal  year  ending  December  31,  2002,  and for the
transition period from October 1, 2001 to December 31, 2001.

     During the two most recent fiscal years of the Company ended  September 30,
2001,  and the subsequent  interim period through April 15, 2002,  there were no
disagreements  between  the  Company  and  Arthur  Andersen  on  any  matter  of
accounting principles or practices,  financial disclosure,  or auditing scope or
procedure,   which   disagreements,   if  not  resolved  to  Arthur   Andersen's
satisfaction, would have caused Arthur Andersen to make reference to the subject
matter of the  disagreement  in connection with its reports.  Arthur  Andersen's
prior audit report on the  Company's  financial  statements  for each of the two
most recent  fiscal years in the period ended  September  30, 2001  contained no
adverse opinion or disclaimer of opinion and was not modified or qualified as to
uncertainty,  audit  scope,  or  accounting  principles.  A letter  from  Arthur
Andersen  addressed to the  Securities  and Exchange  Commission  stating  their
agreement with the above statements is attached as Exhibit 16.

     During the two most recent fiscal years of the Company ended  September 30,
2001, and the subsequent  interim period through April 15, 2002, the Company did
not consult  with PWC  regarding  any of the matters or events set forth in Item
304(a)(2)(i) or (ii) of Regulation S-B.
