Drugless and radiographer led: the start of a new era for CT coronary angiography.

OBJECTIVE: Since inception CT coronary angiography (CTCA) has required facilitating beta blockers (BB). However, CT technology has improved rapidly as has radiographer and reporter expertise. Using these factors, we instituted a radiographer led cardiac CT service (RLCCTS), without routine BB, which we studied for quality control (QC). METHODS: RLCCTS started October 2021 using a wide detector array CT system, with 20 min slots. QC study was registered with the clinical audit team, University Hospitals Plymouth, CA_2020-21-118. Uniform reporting was agreed including indication, BB administration, demographics, dose length product (DLP) and the coronary artery disease-reporting and data system (CAD-RADS) score. Uncertain CAD-RADS meant a non-diagnostic scan (NDS). Six months of data were collected; stable chest pain (SCP) patients, who have national CTCA QC comparators, were analysed using descriptive statistics. RESULTS: Of 1475 patients, 447 were not SCP patients-known CAD (157); valves (286); removed (4, data incomplete) leaving 1028 SCP patients CTCA for analysis. Demographics-mean age 63 years, body mass index 29, 50.4% women. BB therapy-four patients (two recalls). Overall, 36/1024 or 3.5% were NDS; median DLP 173mGy×cm; mean heart rate (HR) 70 bpm, 99/1024 or 9.7% HR >90 bpm (45% not sinus rhythm). CONCLUSIONS: Quality for RLCCTS was judged by NDS rate and DLP. National QC comparators suggest 4% NDS rate; median DLP for SCPP CTCA 209 mGy×cm. RLCCTS compares favourably. With modern cardiac CT, experienced radiographers and reporters, 'drugless' RLCCTS can deliver 20 min slot CTCA with satisfactory QC indicators.

Early presentation of vertebral osteomyelitis following a transrectal ultrasound-guided prostate biopsy with delayed radiological findings.

A transrectal ultrasound-guided (TRUS) prostate biopsy is a common diagnostic procedure which carries an expected risk of iatrogenic infections. These range from simple urinary tract infections to rare but serious infections requiring an admission to hospital. Here we present a rare case of vertebral osteomyelitis following a TRUS biopsy, with normal initial MRI and bone scintigraphy scans and delayed radiological findings on repeat MRI of the spine.
