Net losses at iCad Inc. (NSDQ:ICAD) widened during the first three months of 2010, as the medical imaging and software company saw revenues slip 9.7 percent from year-ago levels.

The Nashua, N.H.-based company reported a net loss of $1.2 million, or 3 cents per share, on $6.5 million in revenues during the three months ended March 31. That compares with a $1 million net loss, or 2 cents per share, on $7.5 million in revenues during the first quarter of 2009.

One of the few financial bright spots at iCad during the quarter was a rise in service and supply revenues, up nearly $500,000 to $1.3 million from the $825,000 reported a year ago. Company officials attributed the 58 percent gain to growth in the number of installed TotalLook MammoAdvantage systems and other computer-aided cancer detection equipment, as well as more clients signing on for service contracts as device warranties expired.

But the higher service revenues were not enough to offset drops in product sales, film-based revenues and a dip in international sales. CEO Ken Ferry saidmany would-be customers remain wary of a “modestly improving” economy while also weighing the potential impact of recent healthcare legislation.

That uncertainty carried over to iCad officials, who declined to offer any guidance on the company’s financial performance in future quarters. They plan to review that stance after the end of the second quarter and could resume providing guidance at that time, the executives said.
