     On  April  15,  2002,  Bio-Imaging   Technologies,   Inc.  (the  "Company")
determined to dismiss its  independent  auditors,  Arthur  Andersen LLP ("Arthur
Andersen") and to engage the services of  PricewaterhouseCoopers  LLP ("PWC") as
its new independent auditors. The change in auditors will be 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.
