A CT scan for a cat costs $450 to $950 for a single body region in the US, £350 to £750 in the UK and ¥1,200 to ¥3,200 in China, and $700 to $1,300 once anesthesia is added. Head scans sit at the bottom of that band, abdominal scans at the top, and the gap between them is 20 to 40 percent for 3 to 5 minutes of extra scan time. All quotes are 2026 private-practice figures and vary 1.5 to 3 times with city and hospital tier.
Two facts decide whether the scan is worth its price. A CT shows bone, lung and small nodules that plain films miss, and it does so in 10 to 20 minutes of table time. An abdominal ultrasound, by contrast, costs $180 to $380 and answers many soft-tissue questions without anesthesia at all.
The 3 regions priced across 3 regions
| Region | What the fee covers | US (USD) | UK (GBP) | China (CNY) |
|---|---|---|---|---|
| 1. Head and nasal | 0.5-0.6 mm slices, 1 series, pre-contrast | 450-750 | 350-600 | 1,200-2,500 |
| 2. Thorax | 0.6-1.0 mm slices, lung and soft-tissue windows | 500-850 | 400-700 | 1,400-2,800 |
| 3. Abdomen | 1.0 mm slices, 2 series with contrast | 550-950 | 450-750 | 1,600-3,200 |
| 4. Add-on: 2nd region | Same anesthesia event, repeat positioning | 250-450 | 200-380 | 700-1,600 |
Row 4 is the one to notice. Adding a second region inside the same anesthesia costs 50 to 60 percent of a standalone scan, so a cat that needs head and chest is quoted $700 to $1,300 rather than $950 to $1,600 for 2 separate bookings.
Anesthesia adds 20 to 30 percent and needs 3 checks
No cat holds still for 15 minutes in a scanner, so every CT runs under general anesthesia with 30 to 45 minutes of total table time, of which 10 to 20 are the scan itself. That adds $120 to $280 in the US, £100 to £220 in the UK and ¥400 to ¥900 in China, plus pre-anesthetic bloodwork at $60 to $140 and an ECG at $45 to $90 for cats over 8.
Fasting is 8 to 12 hours. A cat with a heart murmur or a resting respiratory rate above 40 needs a cardiology check before booking, and that check at $150 to $300 is not part of the CT quote.
Contrast is a separate 60 to 140 dollars
Intravenous contrast adds $60 to $140 and 8 to 12 minutes of table time, and it is what makes a liver mass or a nasal tumour visible at all. A pre-contrast and post-contrast pair doubles the image series but not the anesthesia, so most protocols run both in the same session.
Renal values are checked first: a cat with a creatinine above 2.5 mg/dL usually gets the pre-contrast series only, which cuts $60 to $140 off the bill but also cuts diagnostic yield on soft tissue.
Radiologist review: 80 to 200 dollars, and worth asking about
An in-house read is included in most fees and comes back in 1 to 2 days. A boarded radiologist's second read adds $80 to $200 and 2 to 5 days, and for a nasal or lung case it changes the report in roughly 1 case in 4. Ask which one the estimate includes before you compare 2 hospitals on price.
Turnaround matters when a surgical decision hangs on it. An in-house read in 1 to 2 days lets a cat with a nasal mass go to surgery in the same week; a 5-day specialist read pushes the operation 1 week later, and some owners pay the $80 to $200 premium purely to compress that wait.
When ultrasound at 180 to 380 dollars is enough
Ultrasound wins on 3 questions: is there free fluid, is the gut wall thickened, is there a mass in the liver or spleen. It loses on lung, bone and deep chest, because air and bone block the beam. A cat with a nasal discharge, a chronic cough or a suspected lung metastasis needs CT; a cat with vomiting and a palpable mass usually starts with ultrasound.
X-rays at $110 to $200 remain the cheapest first step for a cough, and 1 in 3 chest films is followed by a CT anyway once a nodule or a collapsed lobe appears.
Sedation is the middle option and the one owners forget to ask about. A cat that will not lie still for 20 minutes can be scanned with a light sedative at $40 to $90 instead of full anesthesia at $120 to $280, which is why 1 practice quotes $180 to $280 for an abdominal ultrasound and another quotes $300 to $380 for the same images.
Where the 1.5 to 3 times spread comes from
3 factors. Machine: a 16-slice unit in a general practice runs 30 to 50 percent cheaper than a 64-slice unit at a referral centre, and cats rarely need the finer resolution. Tier: a referral or teaching hospital adds 40 to 120 percent. City: a capital-city practice charges 40 to 90 percent above a suburban one 30 km out, and mobile CT services that visit a clinic add a $150 to $400 call-out fee.
The full bill, line by line
For 1 abdominal region with contrast: scan $550 to $950, anesthesia $120 to $280, contrast $60 to $140, pre-anesthetic bloodwork $60 to $140, and a radiologist read $80 to $200. That totals $870 to $1,710, against the $550 to $950 headline. Budget the total, not the headline.
5 questions before you book
- Ask whether the quote includes anesthesia, contrast and the radiologist read, or only the scan.
- Ask for the slice thickness, since 0.5 mm and 1.0 mm answer different questions.
- Check whether a second region is priced as an add-on at 50 to 60 percent.
- Ask who reads the images and how many days that adds.
- Ask whether ultrasound at $180 to $380 would answer the same question first.
A cat with laboured breathing, a swollen face that appeared over 48 hours, or a seizure in the past week needs a visit now, not a scheduled scan. Routine visit pricing sits in the visit frequency guide, spreading a bill of this size is covered in the payment planning page, and the 4 rows above can be run in the cost calculator.

Frequently asked
Why is a CT scan more expensive than an ultrasound?
Equipment and anesthesia. A CT needs a scanner costing 10 to 30 times an ultrasound unit, plus 30 to 45 minutes of general anesthesia at $120 to $280, plus a radiologist read at $80 to $200. An ultrasound at $180 to $380 is done conscious in 20 to 30 minutes, which is why it is the cheaper first step for most abdominal questions and the wrong tool for lung or bone.
Can 1 anesthesia cover 2 body regions?
Yes, and it should when both are needed. A second region added to the same anesthesia costs 50 to 60 percent of a standalone scan, so head plus chest is $700 to $1,300 rather than $950 to $1,600 for 2 bookings. The extra table time is 5 to 10 minutes, and the risk of a second anesthesia is avoided entirely.
What does the headline price usually exclude?
Anesthesia at $120 to $280, contrast at $60 to $140, pre-anesthetic bloodwork at $60 to $140, and a specialist read at $80 to $200. A $550 to $950 abdominal quote therefore becomes $870 to $1,710 all-in. Ask for an itemised estimate with those 4 lines named before comparing hospitals on price.
