Although declining reimbursement led to a fall in sales of 64-slice CT scanners in 2007, practices with sufficient volume can still make their technology investment pay off, thus bringing marketing to the fore in the battle to maintain or increase market share. Despite the decline in sales, 64-slice scanners are still selling, and with recent innovations in the field — such as Toshiba’s Aquilion ONE, a dynamic volume CT with 320 detector rows with 0.5mm elements — the challenge for both new and established practices is keeping the cardiac CT scanner busy enough to at least break even.
