In this publication, imaging activity for the latest month of data is based on submissions up to and including the last working day of the month before the publication.

Over 34.5 million imaging testswere reported in England between the 12 months fromNovember 2012 toOctober2013.

Plain Radiography (X-ray) was most common, followed by Ultrasound, CT Scan, MRI and Fluoroscopy. The following tables give an all-England count of imaging activity by modality for the previous year

Beginning in April 2013, figures for Medical Photography, Nuclear Medicine, PET Scans and SPECT Scans are also included in the monthly report.Please see the definitions section for further information on those tests included.

1. Total of modalities listed in Table 1.1 only. The totals may not always equal the sum of the parts due to rounding.
2. Higher response rates for months in 2012/13 are due to the 2012/13 data having been revised and finalised.
3. In January 2014, it was decided to remove 4 providers from the list of organisations in the 2013-14 tables. This was following a reason to believe that those providers should no longer be included in these tables. In the rare cases where data had been submitted for these organisations, this has been left in for completeness. As a result, the totals for the previous months will not be affected; however the percentage of organisations included for these months has now been updated to reflect this change. Please refer to the additional tables for further information on these organisations.

These tables include the percentage of organisations for which data have been included for each month. Data submitted for some organisations have not been included in the data tables owing to data quality issues, and not all organisations have submitted data each month. Graph 1.2 highlights how the percentage of organisations being included in the data tables has changed over the previous year.

Please see Additional Table 1a-1g(separate Excel file) for a break-down of imaging by modality and by provider.

Patient Test Times

The DID collects data on four dates associated with each imaging event:

- Date of test request (request made by health care professional)

- Date of test request received (by the organisation providing the imaging)

- Date of test

- Date of test report issued (by health care professional interpreting the imaging output)

The Date of Test determines the month an imaging event is reported under in the DID monthly publications.

The median period between the request being made and the test being performed varied greatly for each of the different tests. It varied from the same day for X-ray, Fluoroscopy and Medical Photography tests, to 16 days for SPECT scans and 23 days for MRI.

The following table gives the median number of days between the ‘date of test request’and the ‘date of test’, split by the test modality for each month fromOctober2012 to October 2013.

In the following table, median values of 0 occur where atleast 50% of activity has a 'date of test request' and 'date of test' which is recorded as the same day. Records where either of these dates is missing are not used to calculate median values.

Please see Additional Tables 2a-2g (separate Excel file)for the median number of days between ‘date of test request’ and ‘date of test’ for imaging activityby modality and by provider.

These figures should notbe compared to “waiting time” statistics that measure how long patients are on a waiting list, since these figures include both planned and unplanned imaging activity. In addition, these figures may not have been adjusted for any cancelled or missed appointments and they count the period for each individual test not each patient appointment.

The median period for the report to be issued after the test was the same day for CT scan, Ultrasound and Fluoroscopy, within a day for X-ray, and within two days for MRI.The following table gives the median number of days between ‘date of test’ and ‘date of test report issued’, split by the test modality for each month October 2012 to October 2013.

In the following table, median values of 0 occur where at least 50% of activity has the same day for both 'date of test' and 'date of test report issued date'. Records where either of these dates is missing are excluded from the calculation of median values.89.4% of all records for tests performed in October 2013 included both of these dates.

Imaging Tests that could contribute to Early Diagnosis of Cancer

A main driver for the creation of the DID is to assess use of diagnostic imaging that could contribute tothe early diagnosis of cancer, and in particular,General Practitioner (GP) direct access to these tests. To enable this analysis a subset of procedures particularly used to identify or discount a diagnosis of cancer have been identified:

Brain (MRI)

• This may diagnose brain cancer, this includes – MRI of brain (often with contrast);

Kidney or bladder (Ultrasound)

• This may diagnose kidney or bladder cancer, this includes – ultrasound of kidney, ultrasound scan of bladder or ultrasound and doppler scan of kidney;

Chest and/or abdomen (CT)

• CTs which may diagnose lung cancer, this includes- Chest + Abdominal CT, CT of chest (high resolution or other), CT thorax + abdomen with contrast, CT thorax with contrast or CT chest + abdomen;

Chest (X-ray)

• This may diagnose lung cancer, this includes– Plain chest X-ray only;

Abdomen and/or pelvis (Ultrasound)

• This may diagnose ovarian cancer, this includes – Ultrasonography of pelvis, Ultrasonography of abdomen (upper, lower or other) or abdomen + pelvis.

Note, brain MRI, chest x-ray, and ultrasounds of the abdomen and pelvis to diagnose Ovarian Cancer are three of the key tests which are outlined in Improving Outcomes: a Strategy for Cancer.

Although these tests are used to diagnose cancer, many of the tests also have wider clinical uses. Within thisdata, it is not possible to distinguish between the different uses of these tests.

Over a quarter of tests (25.9%) in October 2013 that may have been used to diagnose or discount cancer were requested by GPs under direct access arrangements. Of these, the most common test requested by GPs was Chest X-ray, followed by diagnostic tests that may have been used to diagnose ovarian cancer(46% of which were requested by GPs).

The following table gives a count of tests carried out on NHS patients that may have been used to make an early diagnosis of cancer. It includes the total number of these tests carried out, regardless of patient source setting, and a subset of this total; where the patient source setting was recorded as “GP Direct Access”.

1. Higher response rates for months in 2012/13 are due to the 2012/13 data having been revised and finalised.
2. In January 2014, it was decided to remove 4 providers from the list of organisations in the 2013-14 tables. This was following a reason to believe that those providers should no longer be included in these tables. In the rare cases where data had been submitted for these organisations, this has been left in for completeness.

With the exception of Chest X-ray, for the key tests that may be used to diagnose or discount cancer, the median period from a test being requested to being performed is longer for GP direct access compared with all referrals. The main reason for this difference is that‘all referrals’ includes tests on emergency admissions and inpatients, which have shorter waits.

Records where either of these dates is missing are excluded from the calculation of median values.89.5% of recordsin October used in creating table 6.1 included both of these dates.
