Real time B-mode ultrasonography is a non-invasive diagnostic imaging modality that does not use radiation and allows examination of various soft tissue structures. For many years it is used in human dermatology and in the last decade it has entered the canine dermatology arena. Based on the frequency employed, cutaneous ultrasonography may be classified as intermediate- (7-15 MHz) or high-frequency (20 MHz or higher). Using intermediate frequency, the ultrasonographic features of normal canine skin are consistent and three distinct visible layers can be seen. Using a 50 MHz transducer, the epidermis and hair follicles are also identified and accurate measurements of skin thickness can be obtained. The aim of this article is to review the available published knowledge regarding ultrasonographic examination of the canine skin.

Background: The purpose of this case report is to describe the potential that metabolomics breath analysis may have in cancer disease monitoring. The advances in mass spectrometry instrumentation allow the accurate real-time analysis of volatile metabolites exhaled in the breath. The application of such non-invasive devices may provide innovative and complementary monitoring of the physio-pathological conditions of cancer patients. Case presentation: A 59-year-old Caucasian woman with spindle cell malignant mesenchymal sarcoma of the presacral region started a first-line therapy with non-pegylated liposomal doxorubicin and ifosfamide associated with pelvic radiant treatment. After two cycles of chemotherapy plus radiotherapy, a significant pulmonary disease progression was reported. Thus, a second-line therapy with trabectedin was administered. However, after only two cycles of treatment a re-staging computed tomography scan reported further cancer disease progression of the target pulmonary lesions as well as occurrence of new satellite bilateral nodules. Real-time analysis of breath exhaled volatile organic compounds, performed by select ion flow tube mass spectrometry (SIFT-MS) during the follow-up of the patient, showed a specific metabolic pattern not observed in the breath of other soft tissue sarcoma patients who achieved clinical benefit from the treatments. Conclusions: This case report revealed the importance of the non-invasive real-time volatile organic compounds breath analysis to distinguish individual specific chemo-resistance phenotypes among soft tissue sarcoma patients. Such observation seems to suggest that breath metabolomics may be particularly useful for monitoring cancer disease progression in soft tissue sarcoma patients where only cost-effective diagnostic tools, such as positron emission tomography and computed tomography, are available.

Scanning Technique

Fungal infections in both their invasive and non-invasive forms can prove difficult to diagnose. The often characteristic appearances on imaging are of great assistance. CT is the primary imaging modality and is probably more accurate than MRI in diagnostic specificity and determining the extent of bone erosion. However this may require a modified scanning technique to adequately demonstrate the typical soft tissue density variations of fungi. MRI should be used to supplement CT when intra-cranial or intra-orbital extension is suspected.

ABSTRACT The prenatal diagnosis of fetal bone and small parts is a challenging task to the variable disorders and large number of possible diagnosis. Fetal limb anomalies may be congenital or acquired in utero. The former occur as anomalies either systemically or, in some limbs, due to hereditary or sporadic impairment in the formation or development of bone, cartilage or soft tissue. Acquired anomalies are caused by mechanical factor of an amniotic band or oligohydramnios. Both types present functional and cosmetic abnormalities, and skeletal dysplasia in particular includes lethal diseases, which makes prenatal diagnosis in such cases highly important, both medically and societally. Diagnostic imaging for prenatal diagnosis is accomplished by ultrasound, MRI and CT scan, and chromosomal and genetic diagnosis is also performed as needed. We focus on skeletal dysplasia to review prenatal diagnosis of fetal bone and small part anomalies by noninvasive ultrasound. For the authors as perinatologists, this is the imaging modality of choice.

The histological examination method is the «gold standard» in evaluating of age-related skin changes, however in most cases biopsy is an unacceptable option by ethical reasons. An alternative option are non-invasive diagnostic methods, in which the evaluation of changes can be carried out in real time without damaging the skin. Nowadays, such methods as high-frequency ultrasound, optical coherence tomography, laser scanning confocal microscopy, magnetic resonance imaging are used. In addition to the above-mentioned methods, it is necessary to hold a standardized clinical evaluation and determination of the physiological parameters of the skin. The evaluation of age-related skin changes of face zone and neck zone before and after the application of the combined erbium and neodymium laser exposure on the «Fotona» apparatus using the «Fotona 4D» technique has been held. There were 80 examined patients aged from 32 to 66 who, after a comprehensive clinical examination, conducted 2 procedures using the «Fotona 4D» method with an interval of 1 month. There was a significant decrease in the index of evaluation of age-related facial skin changes in the process of correction, which indicates a pronounced clinical effectiveness of the proposed technique (27 points at the screening stage and 12 points at 2 months after correction). There was also a normalization of skin moisture and an improvement in relief, reduction of pore diameter and pigmentation area. Analysis of high-frequency ultrasound data showed a statistically significant increase in skin thickness, mainly due to the dermis.

Chapter 128 discusses US-guided musculoskeletal (MSK) procedures. US is an effective imaging modality to guide MSK interventions, such as joint and soft tissue injections and aspirations. Preferred anatomical approaches for needle access for arthrocentesis, injection of contrast for MR arthrography, or injection of local corticosteroid for antiinflammatory effects to different joints are reviewed. A comprehensive US scanning of the targeted area should be performed prior to the intervention. Linear high-frequency transducers provide better detail in superficial locations, but curvilinear array transducers may be needed when targeting deeper structures. Aspiration of abscesses, hematomas, and ganglion cysts, and soft tissue biopsies are readily performed with US guidance. US guidance is effective for lavage and aspiration of calcific tendinosis and for guiding more novel interventions such as platelet-rich plasma injections for degenerative overuse injuries to the tendons and muscles.

Microwave tomography (MWT) is an emerging biomedical imaging modality with great potential for non-invasive assessment of functional and pathological conditions of soft tissues. This paper presents a review of research results obtained by the author and his colleagues and focuses on various potential clinical applications of MWT. Most clinical applications of MWT imaging have complicated, nonlinear, high dielectric contrast inverse problems of three-dimensional diffraction tomography. There is a very high dielectric contrast between bones and fatty areas compared with soft tissues. In most cases, the contrast between soft-tissue abnormalities (the target imaging areas) is less pronounced than between bone (fat) and soft tissue. This additionally complicates the imaging problem. In spite of the difficulties mentioned, it has been demonstrated that MWT is applicable for extremities imaging, breast cancer detection, diagnostics of lung cancer, brain imaging and cardiac imaging.
