Contrast material-enhanced three-dimensional (3D) magnetic resonance (MR) angiography of the supraaortic arteries with randomly segmented central k-space ordering (ie, contrast-enhanced timing-robust angiography [CENTRA]) was performed in 16 patients. CENTRA enabled reliable depiction of the aortic arch up to the circle of Willis at high spatial resolution… (More)
OBJECTIVE To detect regional metabolic changes that resemble the expected spatial pattern of neuronal loss in patients with Alzheimer disease (AD). METHODS Thirty-four patients with AD and 22 healthy control subjects were included in the study. Single-slice fast proton spectroscopic imaging was performed in parallel angulation to the temporal lobes.… (More)
Perfusion imaging (PI) demonstrated increased perfusion and diffusion-weighted imaging (DWI) showed high signal limited to the left temporoparietal cortex in a 68-year-old man with nonconvulsive status epilepticus. The EEG showed a slow delta-wave focus. The patient recovered and PI, DWI and EEG changes completely resolved.
This case describes a patient with a traumatic crown fracture of an upper incisor, associated with a laceration wound in the lower lip, showing local oedema. While palpating the tissues of the lower lip we felt the presence of a foreign body. This was confirmed by a radiograph of the lip that showed a radiopaque material, being similar to the coronal… (More)
189 non-palpable breast lesions in 182 patients were localized using conventional mammographic apparatus, a wire grid compression plate and a cannula with a hooked mandrin. The technique of the examination for defining the lesion in three planes and fixation of the lesion with the wire is described. In 173 instances (91.5%), the lesion was found at the… (More)
BACKGROUND AND PURPOSE Cerebrospinal fluid (CSF) tau and neurofilament light chain (NF-L) proteins have proved to be reliable biomarkers for neuronal damage; however, there is a strong need for blood-based tests. METHODS The present study included 132 autopsy cases with rapidly progressive neurological syndromes, including Alzheimer disease (AD) (21),… (More)
Echogenic liver lesions are common. The differential diagnosis has to consider hepatic lipoma, which can be identified by CT.
The combined use of perfusion imaging (PI) and diffusion-weighted imaging (DWI) is opening a new window into the processes that occur during the first hours of ischemia. DWI detects changes in molecular diffusion associated with cytotoxic edema. PI characterizes the degree of regional hypoperfusion. Regions showing mismatches between DWI and PI, i.e.… (More)
The aim of this work was to study the prevalence and clinical presentation of root fractures in a series of patients with dental trauma. Treatment strategies were classified and outcomes after a 6-month period presented. The study population comprised 76 patients (between the ages of 2 and 55 years) with 93 root fractures in their teeth (18 primary, 75… (More)
Our purpose was to compare the detectability and detection rate of acute ischaemic cerebral hemisphere infarcts on CT and diffusion-weighted MRI (DWI). We investigated 32 consecutive patients with acute hemisphere stroke with unenhanced CT and DWI within 6 h of stroke onset. The interval between CT and DWI ranged from 15 to 180 min (mean 60 min). Infarct… (More)
