Congenital heart disease in newborns is associated with global impairment in development.
We characterized brain metabolism and microstructure, as measures of
brain maturation, in newborns with congenital heart disease before they underwent
We studied 41 term newborns with congenital heart disease — 29 who had transposition
of the great arteries and 12 who had single-ventricle physiology — with
the use of magnetic resonance imaging (MRI), magnetic resonance spectroscopy
(MRS), and diffusion tensor imaging (DTI) before cardiac surgery....
(BQ) Part 1 book "Brain Imaging with MRI and CT" presents the following contents: Bilateral predominantly symmetric abnormalities, sellar, perisellar and midline lesions, parenchymal defects or abnormal volume.
(BQ) Part 2 book "Brain Imaging with MRI and CT" presents the following contents: Abnormalities without significant mass effect, primarily extra axial focal space occupying lesions, primarily intra axial masses, intracranial calcifications.
Clinical course of CLL is variable. Recently, progress has been made in the identification of
biological markers that could predict disease progression. Particularly, the expression of
unmutated Ig genes, some cytogenetic abnormalities like 17p and 11q deletions and the
expression of the zeta-associated protein 70 (ZAP-70) are associated to a poor prognosis.
Govender et al. present an important overview of criteria employed to predict
recurrence and progression to MS, with particular attention given to radiological
findings. Guevara Campos and González Guevara focus specifically on Landau
Kleffner syndrome (LKS; sometimes called infantile acquired aphasia), in which
language comprehension and expression impairments emerge after an initial period of
In Chapter 5, Carrascosa Romero and de Cabo de la Vega consider the relevance of
genetics and brain imaging findings in the diagnosis of diseases which result from
abnormal development or neoplasia of cells derived from the neural crest
(neurocristopathies). Koga and Saito (Chapter 6) provide a beautifully illustrated
discussion of the use of neuroimaging tools to guide gamma knife radiosurgery.

The advantages and limitations of conventional structural MRI for the diagnosis and
monitoring of MS are discussed by Andreadou (Chapter 15). There is often a disparity
between the level of structural abnormality seen on MRI and level of cognitive
difficulties expressed by the patient with MS. Clinical interview and
neuropsychological assessment are vitally impairment, not only from an initial
diagnostic perspective but also in terms of longer term planning and care.
These disorders are caused by maturational white matter abnormalities and therefore
white matter tractography (using DTI) can offer advantages over conventional MRI in
the detectability of clinically relevant microstructural features. High field strength
structural MR scanning (up to 7 tesla for clinical and research use in humans) is now
available in some countries, and this greatly enhances the spatial resolution over that
offered by standard clinical facilities (typically 1.5 or 3 tesla).
While history and examination will always remain the foundation of neurolog-
ical diagnosis, MRI and CT have now become the most important diagnostic
tests used by neurologists and neurosurgeons. These tests are critical not only
for confirming clinical diagnosis, but in many cases will give additional infor-
mation absolutely essential to patient care. Modern clinical diagnosis and treat-
ment of central nervous system disorders relies heavily upon neuroimaging. In
some cases, the optimal management of clinical problems affecting patients
with brain tumors, strokes, etc.
Evaluation of Patients with Pathologic Vestibular Vertigo The evaluation depends on whether a central etiology is suspected (Table 22-2). If so, MRI of the head is mandatory. Such an examination is rarely helpful in cases of recurrent monosymptomatic vertigo with a normal neurologic examination. Typical BPPV requires no investigation after the diagnosis is made (Table 22-1).
Clinical Presentation and Staging Patients with cervix cancer generally are asymptomatic, and the disease is detected on routine pelvic examination. Others present with abnormal bleeding or postcoital spotting that may increase to intermenstrual or prominent menstrual bleeding. Yellowish vaginal discharge, lumbosacral back pain, lower-extremity edema, and urinary symptoms may be present.
The staging of cervical carcinoma is clinical and generally completed with a pelvic examination under anesthesia with cystoscopy and proctoscopy.
Obtaining an accurate 24-hour-sleep-wake history is extremly important. History should be
focused also on relevant factors as medical history, compensation of epilepsy, type and
frequency of epileptic seizures, their incidence according to circadian cycle and actual
antiepileptic medication, or other drug and medication use. Also social, enviromental or
psychological conditions, which may interfere with sleep quality, should be evaluated.
Neurological examination in connection with neuroimaging methods (MRI) can detect
cerebral leasions as the reason of sleep problems.

Unilateral aplasia of both cruciate ligaments
Maurice Balke1*, Jonas Mueller-Huebenthal2, Sven Shafizadeh1, Dennis Liem3, Juergen Hoeher4
Abstract Aplasia of both cruciate ligaments is a rare congenital disorder. A 28-year-old male presented with pain and the feeling of instability of his right knee after trauma. The provided MRI and previous arthroscopy reports did not indicate any abnormalities except cruciate ligament tears.
MRI and its derivatives have demonstrated important
findings in ASD as has been reviewed extensively
[13-16]. The earliest anatomical studies involved recog-
nition that young children with ASD have abnormally
increased total brain volumes that appear related to
both increased grey and white matter volumes, with a
differentially higher white matter contribution. Brain
size in ASD appears to reach a 10% increase beyond
control values by two to four years of age, possibly fol-
lowed by a plateau.
