Clinical Trial
99mTc-DPD-SPECT/CT predicts the outcome of imaging-guided diagnostic anaesthetic injections: a prospective cohort study.
We hypothesized that bone SPECT combined with multiplanar reconstructed CT can identify and target the pain-inducing focus in the foot and can be used to successfully guide anaesthetic infiltrations. Therefore we prospectively investigated feasibility and predictive value of bone SPECT/CT for image guided diagnostic infiltrations in patients with chronic foot pain. ⋯ The present study shows the feasibility of 99mTc-DPD-SPECT/CT guided infiltration of osseous structures of patients with chronic foot pain. 99mTc-DPD-SPECT/CT had a higher predictive value on the clinical outcome than the clinical assessment. In the clinical setting 99mTc-DPD-SPECT/CT might overrule the clinical assessment in case of disagreement on the target lesion.

Comparative Study
Tracheal morphology and collapse in COPD: correlation with CT indices and pulmonary function test.
To assess the tracheal morphologic changes using CT in COPD (chronic obstructive lung disease) patients and to assess correlation between them and PFT (pulmonary function test) and CT parameters. ⋯ Among the tracheal morphologic changes, the most significant change in COPD patients compared with that in the control group, was the TI. In COPD patients, the tracheal morphologic change showed clinically significant correlation with severity of emphysema and CT indices.

Comparative Study
Arterial spin-labeling MR imaging in moyamoya disease compared with SPECT imaging.
Arterial spin-labeling (ASL) is a noninvasive magnetic resonance (MR) imaging method used to obtain brain perfusion information on various cerebrovascular diseases. We retrospectively compared the use of ASL-MRI and single-photon emission CT (SPECT) imaging to determine absolute cerebral blood flow (CBF) in moyamoya disease. ⋯ Although the ASL-value was lower than the rest-IMP-value, the significant relationship between the ASL-value and the rest-IMP-value may suggest that perfusion imaging by ASL-MRI could be used to recognize the condition of brain perfusion. In particular, the stronger correlation coefficient between the ASL-value and ACZ-IMP-value might suggest that perfusion imaging by ASL-MRI could show the potentially dangerous zone for ischemia.

Case Reports
Transarterial Onyx packing of the transverse-sigmoid sinus for dural arteriovenous fistulas.
To report transarterial Onyx packing of the transverse-sigmoid sinus for dural arteriovenous fistulae (DAVFs). ⋯ Transarterial Onyx packing of transverse-sigmoid sinus for DAVFs via the meningeal arterial system is a safe therapeutic alternative in selected cases.

The aim of this study was to reveal the relationship between intratumoral uptake of gadoliniumethoxylbenzyldiethylenetriaminepentaacetic acid (Gd-EOB-DTPA) of hepatocellular carcinoma (HCC) in the hepatobiliary phase and pathological features. ⋯ The area of Gd-EOB-DTPA uptake does not always match the greenish part, but HCC with uptake of Gd-EOB-DTPA significantly correlated with green HCC.
