To evaluate percutaneous computed tomography (CT)-guided intracystic and intra-articular steroid injections for the treatment of lumbar facet joint cyst causing radicular pain. ⋯ Lumbar facet joint cysts are a common feature of back and radicular pain. They may be treated effectively by interventional radiologists using CT guidance. Percutaneous treatment using double injections can save surgery in 75% of patients.

To investigate the changes of dynamic contrast-enhanced MR imaging (DCE-MRI) parameters at 3 T in cervical cancer patients before and after concurrent chemoradiotherapy (CCRT), and to correlate the parameters with final tumour response to therapy. ⋯ • DCE-MRI offers new insights into tumour behaviour. • Changes in tumour size lag behind biomarkers which improve quickly in responders. • DCE-MRI is a non-invasive imaging technique that can characterize tumour vasculature. • DCE-MRI of cervical cancer may be useful in monitoring changes with therapy.
-
To evaluate the safety and efficacy of US-guided high-intensity focused ultrasound (HIFU) ablation for the treatment of submucosal fibroids ⋯ • High-intensity focused ultrasound (HIFU) is a new minimally invasive therapeutic technique. • HIFU ablation may be safe and effective for treatment of submucosal fibroids • Treatment is minimally invasive and repeatable. • Vaginal expulsion of necrotic tissue is common after treatment.
-
To detect symptomatic hemispheres during the postoperative course of subarachnoid haemorrhage (SAH) using arterial spin labelling (ASL). ⋯ • MR arterial spin labelling (ASL) can non-invasively assess cerebral blood flow (CBF) • ASL revealed significant CBF reduction in symptomatic hemispheres compared with asymptomatic hemispheres • Serial ASL measurements enable observation of time-dependent CBF changes after SAH • ASL is non- invasive and suitable for serial repeated examinations.

Comparative Study
Performance of computer-aided detection of pulmonary nodules in low-dose CT: comparison with double reading by nodule volume.
To evaluate performance of computer-aided detection (CAD) beyond double reading for pulmonary nodules on low-dose computed tomography (CT) by nodule volume. ⋯ • Computer-aided detection (CAD) has known advantages for computed tomography (CT). • Combined CAD/nodule size cut-off parameters assist CT lung cancer screening. • This combination improves the sensitivity of pulmonary nodule detection by CT. • It increases the positive predictive value for cancer detection.
